My daughter is gorgeous and great fun but at 12 months she is not crawling or creeping. She can sit without support which happened at about 9 months and in last few weeks has started trying to move about.
She has never been that interested in objects or grabbing and exploring things. She is very affectionate, smiles and laughs lots. Not sure if she knows her name she doesn't always respond when called. She isnt babbling but has a growing range of noises.
I try very hard not to compare. Its difficult to read development calendars that lost all the things she 'should' be doing. Maybe I am over anxious...but would you be worried?
