Your baby’s development
Your baby measures around 8cm from the top of their head to their bottom.
In the following weeks your baby’s proportions will start to resemble a newborn. At the moment their head is quite large and makes up a third of their body size.
When awake, they are very active; stretching, kicking, turning, reaching and grasping with their tiny fingers. Internally, their kidneys are starting to work by sending urine to the bladder.
Fine downy hair begins to develop on your baby’s skin. Their sucking and swallowing reflexes are becoming stronger and your baby’s skeleton and skeletal muscles now hold them more erect.
Although your baby’s arrival is months away, your breasts and milk ducts are already preparing for breastfeeding. They’ll soon start producing thin yellow liquid called colostrum. This is packed with nutrients and will be the first milk that nourishes your baby before your regular milk starts to flow.
Your breasts may feel lumpy as they change and grow in size however, the tenderness of the first trimester is likely to diminish.
