week 20 of my pregnancy - what to expect

You are now half way through your pregnancy -


Your baby is about 16cm and weighs about 260gr. The skin covering your baby begins growing from two layers; the epidermis which is on the surface and the dermis which is the deeper layer. One of these layers contains epidermal ridges which are responsible for the surface patterns on fingertips, palms, and soles and genetically determined. Vernix which covers your baby's body offers the baby's skin protection against the amniotic fluid. Hair is seen on the upper lip and eyebrow and it is usually shed around the time of your baby's birth. Your baby may start to make involuntary movements like grasping or rubbing hands together; such movements are not controlled by the brain.
