Besides a hearing problem, what would be a reason for a 7mo not to coo or babble? she passed the newborn screening & turns to noises but is not vocal.

Don't ignore hearing: The newborn hearing exam is one point in time & provides us with needed initial information on hearing issues that are present from birth. However, there are some conditions that can lead to gradual loss after a few months, even if things were fine at the start.I'd get the hearing re-tested as part of a good evaluation with your dr.Baby should be doing reciprocal oos & ahhs & more as you play.

Good question: Does she smile? Does she make other types of noises (squealing, raspberries, etc)? Cooing usually starts between 4-6 months of age and babbling by 6-11 months of age. Recheck her hearing. Discuss your concerns with her pediatrician. A developmental evaluation would be helpful.
