DD2 is 14mths, very physical, loves climbing, has no sense of danger, and goes into paroxysms of fury when we stop her doing something she wants to do. So, great, determination, tenacity, courage, all wonderful qualities. But she also bashes her head into things (e.g. walls, floors) when she is angry or upset - I would say 'deliberately' but I'm not sure if a 1yr old really knows she has a head. It's been going on about a month, obviously she then gets even more upset. Do you think this falls within the boundaries of 'normal' baby behaviour that will pass, or would you be more worried? Thanks, MNers, in advance.
