Typically develop-: Ing infants have stranger anxiety at 6 mos. ; separation anxiety at 9ps. If your pediatrician has checked him out ; assured you he's healthy, leave him with his dad or another family member for short periods. Say good-bye calmly ; quickly while his dad engages him in play. Calmly say hello when you return. He is old enough for learned behavior. Put him in his own bed to self-calm for sleep.
