7 Weeks: blueberry
Now about 1cm long, the size of a blueberry, your baby has distinct, slightly webbed fingers and toes. He’s a jumping bean, moving in fits and starts. The liver is churning out large amounts of red blood cells until the bone marrow forms and takes over this role.
At seven weeks, your baby enters a very busy developmental stage. Between now and 20 weeks, your baby will be growing rapidly, and body parts that formed in the first few weeks of life (such as the heart and brain) will become more specialized and complicated. Tooth buds, palate and tongue are forming, while his ears continue to develop and eyelids are starting to cover his eyes. Your baby’s skin is paper thin, and veins are clearly visible.
