Now firstly, I know he doesn't mean it. So does DH, deep down, but the longer this goes on I can see he's becoming quite hurt by it. DS's behaviour is currently quite appalling. He's shouting, answering back, point blank refusing to do as he's told, etc. but he's 10 times worse with DH than me.
My explanation is that he has a fairly demanding new baby sister (7 weeks), I am usually a WOHM (DH being a SAHD) and am now at home but spending a very good part of the day breastfeeding DD, and DS is reacting by attention seeking. I think he's rejecting DH because he wants more time with me. I figured we might have been overdoing the "big brother" thing and expecting too much of him so we've really stepped back and we're treating him with kid gloves (within reason), but nothing is helping.
Has anyone else had a young child who's reacted to a new baby like this and how did you solve it? I should add that DS is brilliant with DD - it's his horrible attitude to DH that's the problem.
