My 15 month old ds often pulls my 3.5 yo dd's hair, and as he can do it quite hard it is quite distressing for her. We have tried saying No, firmly, and removing him from the situation, but I am aware that as he is still so little this may just be reinforcing him (any attention is good attention etc....)
Should we just ignore it and hope it is a phase? Has anyone any tips on dealing with him? Thanks in advance...
