All About Baby
Week 10 marks a milestone for your baby-to-be. All her cells have been directed to their placesbrain tissue is growing rapidly, muscles are forming, fingers and toes are becoming defined. At about 10 weeks, Baby's fingernails even start to appear. Soon, she'll have toenails as well. Baby also has eyelidsbut the bottom and top halves have fused together and will keep the eyes shut for several more weeks, like a kitten's. Ears, which (oddly) began developing on the neck, are moving into their normal place on the sides of the head. The baby can now swallow amniotic fluid and its life-sustaining organs (think heart, brain, liver, kidneys, intestines) are beginning to work. And her tiny heart, which already has claim on yours, has all four chambers now.
