When getting ready for a seriously silly round of peek-a-boo or bang the cups together or put the toy on your head, make sure that you are on baby’s level FIRST. If baby is on the floor, so are you. If baby is seated, you may be kneeling. If baby is in a highchair, you can sit across from him.
On his level he can hear your words better, watch your facial expressions more closely and see your mouth moving more clearly. It’s also just more comforting to have a conversation with someone who isn’t leaning over you or who has their back turned or who is talking from the other side of the room.
Play, laugh, tickle, make funny sounds, and have “conversations” at their level.
