Breast Feeding Guide

Important health benefits of breast feeding and lactation have been described for mothers, these include:

• Decreases postpartum bleeding.1
• Encourages contraction of the uterus after birth.6
• Breast feeding may help the mother to return to her pre-pregnancy weight.1
• Breast feeding is associated with a reduced risk of developing pre-menopausal breast cancer and ovarian cancer.1
• Breast feeding may reduce the risk of osteoporosis and hip fracture later in life.1
• A baby sucks at a mother’s breast for comfort and, of course, for milk. Milk “let-down” is a reflex response to the suckling and kneading of the nipple (and sometimes in response to the sight, smell, and sound of the baby).
• It is ultimately affected by the secretion of oxytocin, a hormone secreted by the pituitary gland.7
• Breast milk is readily available at the exact temperature and does not need time to prepare.
• History of lactation is associated with a reduced risk of type 2 diabetes.8,9

Breast milk provides the optimal nutrition for infants in their first 6 months of life and in addition to complementary foods thereafter.

It has been demonstrated that mothers can produce adequate breast milk for their babies, even under sub-optimal conditions. However, breast feeding mothers do have a slightly increased requirement for most nutrients compared to mothers who do not breast feed as many vitamins and minerals in a breast feeding mother’s diet are transferred into the breast milk. Therefore, it is important for the mother to be encouraged to eat adequately to meet her own nutritional needs and to provide nutrition to the infant.

A breast feeding mother should eat regular nutritious meals and snacks to meet the extra energy requirement (approximately 500 calories/day or 2000–2100kJ/day). Consuming a variety of foods each day is important in meeting both the mother’s and infant’s nutritional needs.

It is important a breast feeding mother consumes a wide variety of nutritious food, such as:11

• Vegetables, legumes and fruits.
• Cereals (including breads, rice, pasta and noodles), preferably wholegrain.
• Lean meat, fish, poultry and/or alternatives. • Milks, yoghurts, cheeses and/or alternatives. Reduced fat varieties should be chosen where possible.
• Fluids, especially water.

It is also recommended when following a healthy balanced diet to:11

• Limit saturated fat intake, choose lean meat and unsaturated fat spreads, such as olive/safflower/ sunflower oil-based spreads.
• Choose unsaturated fats that are found in foods such as avocado, nuts and seeds, and olive and sunflower oils.
• Limit high salt foods, such as processed meats, potato chips and adding salt to meals.
• Avoid alcohol consumption, particularly in the first month after the infant is born until breast feeding is well-established.
• Limit intake of sugars and foods containing added sugars, such as high sugar breakfast cereals, lollies or sweets, cakes, biscuits and fizzy drinks.

The energy needs of a breast feeding mother are increased because of milk production. The energy requirements for breast feeding mothers are an additional 500 calories/day or 2.0–2.1 MJ/day assuming full breast feeding in the first 6 months and partial breast feeding after that.10

While it is normal (and expected) that mothers put on weight while pregnant, it is not recommended that mothers follow a weight loss diet while breast feeding. Breast feeding naturally allows for gradual weight loss. If a mother gains weight after birth, it is most likely she is eating too much food, or choosing foods that are excessively high in energy (kilojoules/ calories).

The energy and nutrient needs of a breast feeding mother are increased because of milk production.

Other nutrients of particular concern during breast feeding are:

Protein

A breast feeding mother requires additional dietary protein to ensure there is adequate amount of protein in her breast milk. While the mean protein intakes in both Australia and New Zealand demonstrate that protein intake in childbearing women appearssufficient to meet the additional requirements of pregnancy and breast feeding,11 evaluation of protein requirements should be made on an individual basis. Protein is vital for the growth, maintenance and repair of cells. The Recommended Daily Intake (RDI) for protein for breast feeding mothers is 67g/day (1.1g/kg of body weight).10

Protein is found in a wide range of foods such as meat (including fish and poultry), eggs, dairy, legumes (such as beans, pulses and soy products) and nuts. Smaller amounts of protein are found in grain-based foods such as bread and pasta.

Folate

Folate is a B vitamin needed for healthy growth and development.

The RDI for folate for breast feeding mothers is 500μg/day.10

Folate can be found in leafy vegetables, wholegrains, peas, nuts, avocado and yeast extract spreads (e.g. Promite,® Vegemite,® Marmite®).

Iodine

Iodine is an essential mineral needed for the production of the thyroid hormone which helps in brain and nervous system development.

The RDI for iodine for breast feeding mothers is 270μg/day.10

The NHMRC Australia12 and the New Zealand MOH13 both recommend all healthy pregnant and breast feeding mothers take an iodine supplement of 150μg each day.

Iodine can be found in seafood, milk, iodised salt and vegetables.

Supplements containing seaweed or kelp are not recommended for breast feeding women due to the variability in iodine content and quality.

Zinc

Zinc is a component of various enzymes that help maintain structural integrity of proteins and help regulate gene expression.

The RDI for zinc for breast feeding mothers is 12mg/day.10 Zinc can be found in lean meat, wholegrain cereals, milk, seafood, legumes and nuts.

Vitamin A/Beta-carotene

Vitamin A is vital for normal growth. Vitamin A helps provide resistance to infections.14

The RDI for Vitamin A for breast feeding mothers is 1,100μg/day.10

Vitamin A can be found in milk, cheese, eggs, fatty fish, and organ meats.

Beta-carotene, which enables the body to manufacture vitamin A, can be found in yellow-orange vegetables such as carrots and pumpkin, fruits such as mangoes and apricots and in other vegetables such as spinach and broccoli.

Vitamin B6

Vitamin B6 is important for the metabolism of protein and the formation of red blood cells.

The RDI for breast feeding mothers is 2mg/day.10

Vitamin B6 can be found in meat, poultry, fish, whole grains, brussel sprouts, green peas and beans.

Omega-3

Long-Chain Polyunsaturated Fatty Acids (LCPUFAs) consumed and accumulated in early pregnancy by the breast feeding mother provide a significant addition of LCPUFAs in the breast milk and subsequently the breast feeding babies diet.

The recommendation for Omega-3 for breast feeding is 145mg/day.10 Foods rich in Omega-3 are oily fish, green leafy vegetables, nuts and seeds and some plant oils (soybean, canola, flaxseed and walnut oils).

Water/Fluids

Breast feeding mothers should drink an average of 9 cups of fluid daily10 with the majority coming from water. Fluid intake can be a combination of water, milk, juice and other drinks.

It may be helpful for the breast feeding mother to drink after each breast feed, as well as drinking regularly throughout other times of the day.

Newborn infants need short frequent feeds and will typically feed every 2 to 3 hours (8–12 times per 24 hours) in the early stages. This is because breast milk is easily digested to meet a baby’s continuous demands for brain and body growth and the newborn infant’s stomach is small.

An infant will be getting enough milk if they:

• Have 6–8 wet cloth nappies or 5–6 disposable nappies per 24 hours.
• Have soft bowel motions.
• Generally settle after most feeds.
• Have bright eyes and good skin tone.
• Are gaining weight appropriate to age.

If an infant sleeps for long periods in the day it is important to wake them to feed. All infants have individual needs and a mother’s breast milk adjusts to an infant’s needs. As breast feeding research continues breast feeding practices may change. The current recommendation is to feed a baby from one breast completely first and then offer the second breast. However, some babies will always take both breasts, some will sometimes take both, and others will only take one breast per feed. This is all normal in breast feeding and may in part be due to the individual storage capacity and production of the mother child dyad/bonding.18

It is common practice for a mother to cease breast feeding due to the perception that the infant is not getting enough milk. In most cases the fears are unfounded and the mother can produce adequate milk.

In a small number of cases, if milk supply is reduced it is normally temporary.

Ways to increase breast milk supply include:

• Increase the supply by breast feeding more frequently.
• Ensure the mother is having enough rest.
• Encourage ways to minimise stress and promote well-being.
• Ensure the mother is having plenty of fluids, at least 9 cups per day.6
• Ensure the mother is eating a healthy, well balanced diet.
• Ensure the mother has the most effective positioning.
• Let babies determine length of the breast feed.
• Avoid using pacifiers particularly for extended periods of time.
• Avoid putting babies on scheduled feeds or stopping night feeding too early (before 6 months).
• Express breast milk to further stimulate supply.
• Use lactation aids to feed the baby when possible, rather than using a bottle for supplemental feeds (contact a lactation consultant for more information).
• Encourage skin-to-skin as much as possible

Once breast feeding is well established (usually 4–6 weeks), there may be times where a mother may need or want to express breast milk.

Expressing milk by hand

Before expressing milk, the mother may find that softening her breasts beforehand will help with hand expression. This can be done by applying a warm face cloth, taking a shower or massaging them. The mother’s hands must be cleaned, and a sterilised, wide rimmed bowl is required to collect the milk.

By supporting the breast with one hand then massage down from the top of the breast to the nipple. Work all round it including the underside. Then put gentle pressure on the area behind the areola (the dark skin around your nipples) with the thumb and forefinger.

By squeezing them together and pressing backwards milk should be released. It is important to be aware that the milk can spray in lots of directions.

Expressing milk by manual or electric pump

Using a pump can be quicker and less tiring than using hands. The mother may find that softening her breasts beforehand will help with hand expression. This can be done by applying a warm face cloth, taking a shower or massaging them. The pump should be thoroughly sterilised before expressing. Depending on the pump used, it should take 20–45 minutes and should not cause any pain. It is important to read and follow the manufacturer’s instructions and ensure that the nipple is properly fitted, or expressing can be ineffective and cause damage.

• 4–6 feeding bottles with caps.
• 4–6 teats.
• Teats are available in a variety of shapes and flows
  • it is important to advise the parent or caregiver about the most appropriate one for their infant, or alternatively suggest they speak to their pharmacist.
  • the teats condition should be checked regularly. Teats will wear over time and may need replacing, particularly if an infant has teeth and bites. Discard any teats with cracked collars.
• Bottle brush for cleaning bottles.
• Sterilising equipment – this depends on the sterilising method chosen e.g. either by boiling, using a sterilising solution or microwave sterilising.
• A breast pump may be used to assist in expressing breast milk. Ensure all parts of any equipment used to assist in expressing milk can be effectively cleaned.
• Breast milk bags – sterile bags for storing breast milk in fridge or freezer.

Do not thaw or warm expressed breast milk in the microwave as this destroys the living cells in the milk

There are a number of safe ways to sterilise infant’s feeding equipment. The bottles, teats and collars should always be cleaned first to ensure no traces of milk or milk residue remain.

Steam

Electric steamers sterilise bottles in 8–12 minutes. They leave no unpleasant smell or taste but are not suitable for all equipment (i.e. breast pumps). It is important to ensure the openings of the bottles and teats are facing downwards in the steriliser and that the manufacturer’s instructions are followed.

Microwave

Steam sterilising units create steam in the microwave which sterilises bottles and teats in 8–10 minutes. It is important to follow the manufacturer’s instructions, especially concerning the correct amount of water to use.

This method is not suitable for glass bottles, as glass retains heat and can become extremely hot in the time it takes to sterilise. Teats should be placed upright not laid flat, as this allows the steam to circulate to all areas of the teat.

Boiling

To sterilise a bottle by boiling, completely submerge all the feeding equipment in boiling water for 5 minutes.

The water should cool before taking the equipment out and then shake off excess water. Cold water Using an approved sterilisation tablet takes about 30 minutes and is highly safe and effective.

It is important to prepare the sterilising solution according to the manufacturer’s instructions.

The solution should be made up in a large glass or plastic container.

It is important that the bottles and teats are fully submerged in the container (no air gaps).

The bottles can stay sterilised in the water for up to 24 hours.

Do not thaw or warm expressed breast milk in the microwave as this destroys the living cells in the milk.

• Do not thaw or warm expressed breast milk in the microwave as this destroys the living cells in the milk.
• Frozen breast milk can be thawed in the refrigerator or alternatively in a bowl of warm water.19 Sterilise the cup or bottle before decanting the thawed breast milk.
• Thawed breast milk should be used within 24 hours and should not be refrozen. If not used, it should be discarded.19
