Your baby at 11 weeks
The baby grows quickly and the placenta is rapidly developing – it'll be fully formed at about 12 weeks.
The bones of the face are formed now. The eyelids are closed and will not open for a few months yet.
The ear buds developing on the sides of your baby's head look more like ears as they grow.
Your baby's head makes up one-third of its length, but the body is growing fast – it's straightening, and the fingers and toes are separating. There are fingernails.
