Does your 7 month old wave bye, blow kisses, repeat gestures when encouraged???
My daughter will be 9 months old tomorrow and she doesn’t wave bye bye or blow kisses yet! I wouldn’t worry, they all do it at their own pace. I’ve read a lot of your questions and you sound like a great mommy who is involved and concerned for your daughter’s well being, I’m sure she is right on track! Just keep showing her how to wave good bye and blow kisses, eventually she will catch on.
