Dr. Carole Keim MD introduces everything to know about babies at 9 months of age in this episode. She details developmental milestones and safety considerations for the 9 to 12 month age range and lets you know what to look for.

Dr. Keim encourages parents to have date nights at this stage, to leave your baby with a trusted sitter, and also to start really talking out any parenting differences that may have appeared. She talks about all the ways in which your baby will have developed, from object permanence to repetitive sounds, and covers sleep, nutrition, and teeth as well. This is the age to really start baby proofing your home with outlet covers and stairway gates, and Dr. Keim also shares advice on skincare and the 9 month check up.
