They used to get on so well, but the last few weeks have been a nightmare, all they do is hit and shout at each other, even nursery have commented that they are not getting along, any tips on what I can do? I have no way of seperating them for a while, either myself or dh are always at work, Id like for me to take one out and dh take the other out somewhere seperate for a few hours but we never get the chance.
