Your baby is now starting to store fat underneath their skin. This will help to keep them warm and provide energy so make sure you are including healthy source of fat in your diet.
This week your baby's fat stores are beginning to develop under their skin. The fat will provide energy and help to keep your baby warm after birth. Their retina has become more sensitive to light and their eyes are looking forward now but they are still firmly closed. A substance called Meconium which is made up of products of cell loss, digestive secretion and swallowed amniotic fluid is now forming in the bowel and will become your baby's first stool after birth.
Fat is an essential part of a healthy diet - whether you are pregnant or not. It can receive a lot of bad press but really problems only arise if we eat too much of it or if we choose the more unhealthy fats such as from fried foods or cakes, biscuits etc. Limit these fats but include healthier fats such as from oily fish, rapeseed or olive oils and nuts and seeds. These will give you energy, lay down your own fat stores and omega-3 fats are important for your baby's brain and eye development.

Speaking to your baby each day will help them to get more and more familiar with your voice and when you welcome them to the world they will know that familiar sound. Make sure to get Dad talking to your bump too!
The sweet taste of amniotic fluid means that babies naturally have a preference for sweeter flavours once born
