Sometimes, babies cry even when they've been fed and had a diaper change. This can leave parents perplexed and frustrated trying to find a way to calm their child down. Research has shown that babies respond well to motion and sound. A child in the womb is still able to feel vibrations and noise. The baby can hear the pounding heart, the stomach gurgling and the rush of blood. The womb is not a silent place for babies so don't worry about turning on some music for your baby. As this video shows, music is actually a great way to get a positive response from your baby, and using music and rhythm can be a great way for parents to find ways to soothe and bond with their baby.
