Im worried my almost 12 month old is regressing in her skills. She used to clap multiple times a day, sometimes on command or in imitation of us but here recently she wont do it hardly at all. She also used to wave on command and now wont either. She just randomly waves her hand throughout the day, i dont think directed at anything. I just overall am worried she is going backwards instead of forwards. She also isnt babbling and hasnt been for over a month. She has started showing me toys more sometimes but not consistently. Should i be worried?
