Ultrasound: baby's first smile
Smile! A 4-D pregnancy ultrasound captures babyís first smile. While experts used to think that babies learned to smile after birth by copying their parents, it is now believed that babies smile in the uterus because it is a safe, stress-free environment.
When you smile at your baby, she smiles back. Parents are one of the most important resources a baby has when it comes to developing social skills. As your baby grows, he will overcome a series of developmental milestones and begin to communicate by cooing, babbling and waving her arms.
