Breastfeeding is the best for babies and a healthy diet / maternal nutrition is important when breastfeeding. A decision not to breastfeed can be difficult to reverse. Infant formula is suitable from birth when babies are not breastfed. It is recommended that all formula milks be used on the advice of a doctor, midwife, health visitor, public health nurse, dietitian, pharmacist, or other professional responsible for maternal and child care and the financial implications should be considered. All preparation and feeding instructions should be followed carefully as inappropriate preparation could lead to health hazards.

13 Weeks Pregnant

Your baby’s development

During this stage of pregnancy, breasts can start to feel a bit lumpy – but don’t worry, it’s just that your mammary glands and ducts are developing in time for the birth. Your breasts may already have started making a thin yellow liquid called colostrum. This is packed with nutrients and will be the first milk that nourishes your baby after the birth before their regular milk starts to flow.

You & your body

Your growing baby now measures around 8cm. They’re now very active, and stretching, kicking and turning, although they’re still far too small for you to feel it. The kidneys are starting to work and are now starting to send urine to the bladder.

Each week, your baby’s proportions become much more like that of a newborn baby, and their head is now about a third of the size of their body.
