Week 17
About the size ofa banana
Your baby can now tell light from dark. Your baby is now 18 cm and 150 grams.
Your baby now grows about two centimetres a week on average. Although the eyes are still closed, your baby has recently become able to tell light from dark, right through the eyelids, the amniotic fluid and the walls of the womb and abdomen. So when you are sitting in the sunshine, your little one will certainly notice it too!
