Pediatrician Dr. Cindy Gellner goes over speech and language development for babies and toddlers. She talks about what to expect your baby to be saying depending on how old they are and what to do if they’re not being as vocal or responsive to sounds. She talks about speech problems that might be concerning—using actions such as pointing, but no words, imitating sounds but not using words, and so forth. She shares the single most important thing a parent can to do help kids improve language skills.
