My dd is a year old (was 1 on the 6th Oct). It's probably a bit young to be worried about behaviour like this but...
she always seems to be the one who is pushing/hitting other children. At the CM's, even though she is the youngest, she rules the roost! Today we had a little party and she was constantly pushing my friends daughter who is 6 weeks older than her. She's also started pinching me.
Just a few things -
a) do you feel like your always apologising for your child pushing other children, or are you the one picking your child off the floor
b) at one point should I become really worried about her behaviour, rather than just joking that I'll be sat in the headmasters office in a few years time due to her picking on other kids
c) how the hell do I stop a 1 year old pinching?!
