DD1 (2 yrs) is pinching baby (4 mths). I (naturally!) find this upsetting and it makes me quite angry. I try not to leave baby in vulnerable position, but being on my own with them most of the time, it does inevitably happen. I tell DD firmly it is not good, I am not happy with this, it hurts your sister, etc. but this hasn't helped. I do try to not make it into a big thing as the negative attention makes DD even more keen. Often happens during breastfeeding. Anyone else been in this situation, how did you deal with it? Advice in general? Thanks.
