Week 17

This week your little one weighs in at around five ounces and stretches to just over five inches (crown to rump). Around this time your baby's ears pop from his head and Baby-to-be can now sense sounds. After all, he has plenty to listen to in utero! He's accustomed to the strong beating of your heart, blood rushing through your veins, and your stomach grumbling. He can also discern sounds outside the uterus, like your voice and music. Although, according to the Mayo Clinic, whether he can distinguish the sound of your voice versus other sounds is not yet clear.
