BabyPod is a silicone, hypoallergenic FDA approved device that, according to studies, helps babies vocalize. Moms-to-be can start using BabyPod at 16 weeks of pregnancy.

"BabyPod is safe and it should only be avoided in high-risk pregnancies, or if the patient has contractions, a dilated cervix, or any kind of vaginal or urine infection," said Dr. Leonardo Marques, a gynecologist and leader of Institut Marques.
