I know this is probably normal and an age old problem, but it's quite upsetting :(
We have DS 11, DD 8 and DD 3. DS seems increasingly intolerant of DD1-can't speak in a civil way to her-is annoyed by everything she does and seems so unkind. He is a lovely boy to everyone else (especially DD2-which makes it more noticeable). It is worse at the moment because everything he gets into-various PC games/x-box things/films-she begins to like and then they are competing for time, eg on the x box (of which there is only one in the house-I'm sure getting another would NOT solve the problem!)
I try to make sure he speaks nicely to her and isn't horrid, but that doesn't help at all and I think makes him more cross with her when I'm not there. I just keep thinking that I might die (the logical thoughts you have!) and they will never speak again! I know she can be annoying-but he seems to really dislike her and she is a lovely girl :(
Is there anything I can do to encourage their friendship?
