Weekly Development Progress
Your baby's about 5.5 inches from head to toe, although when you go for your ultrasound the sonographer may measure from head to bum, as it's much easier due to the curled up position your baby is in. Your newborn will remain in this shrimp-like position for a few weeks after the birth, until they realise they have room to spread themselves out.
Weighing in at about 6.5 ounces, your baby is getting heavier by the day. The main activity at the moment is putting on fat, as your baby's organs continue to mature and grow. Adding fat and putting on weight keeps your baby nourished, healthy and warm. Once he or she has enough fat, the fine hair covering the body will start to vanish, as it's no longer required for warmth. The fat is also helping the skin to become more opaque, although at this point the blood vessels inside your baby can still easily be seen - that's if you could peek into your uterus, of course.
