#AskTheExpert my 9 month old from last 20 days is nodding her head with force. some days she does manytimes other days she hardly does. we got EEG done which came normal. she otherwise sits, crawls, pulls herself to stand with support, stands unsupported for few secs, smiles, babbles and recognizes her name. could this head movement still be problem or indicates infantile spasm. worried please suggest
