Hi ! For a few months now my 18 month old son has been pinching or scratching my other son and over the last week it has been terrible. Ds1 is quite a gentle boy.... He has never hurt ds2 on purpose, although there is friction when they play together (e.g. They both want a paricular toy). I can understand it in this example, but in the last week ds 2 has been doing it all the time, pretty much whenever ds 1 goes near him. Any advice would be most appreciated... It's really upsetting and I hate seeing it as I want them to get along ! So far, I have tried reminding ds2 to be gentle, and showing how to be, and more recently I have tried 'if you do that again I will put you on the floor' .
