#AskTheExpert My 9 month old from last 20-25 days is nodding her head on and off like somedays she will not do at all. other days she will do it again and again, even while playing.she is alert and not irritated by moves. We got basic EEG done which was normal. She otherwise can sit, crawl, pulls to stand, walks with support and stands without support for few secs. she babbles, smiles, Recognizes her name, imitates sounds and action. please suggest if this nodding is normal activity for this age.
