I posted this under beh'r/devel'ment under a different title but haven't had much response and feeling desperate so have posted it again here.
Our bright 2.10 year old's behaviour has recently got a lot worse and I'm thinking it's because our 7 month old has recently started at DS1's nursery. Things did get bad for a while after DS2 was born but seemed to settle down. We attributed it all to sibling rivalry and tried our best to make DS1 feel loved and important. Maybe we were a bit too soft on him as things are getting a bit worse this time round.
He's lovely to his little brother, gives him hugs and kisses, is fiercely protective of him at nursery and I can honestly say we've never been concerned about his behaviour toward him. However, towards me and DH he's becoming rude, argumentative, contrary, very bossy and quite unpleasant to be around at times. He's also regressed a bit and when not being any of the above, he's clingy, always wanting to be picked up and carried around, wants undivided attention just when we're having to feed DS2, change his nappy or generally play with him.
Then on Sunday he poo'ed in his pants and didn't tell us (couldn't smell it) and we only discovered it at bathtime. We're doing the whole reward chart thing at the moment with regard to toileting but have been for a while so this is nothing new to him. We have had a few wee accidents both at home and at nursery but he's never done this before.
I wondered if any of you had been through this and could it be sibling rivalry? All his attitude is directed at us. We've done the naughty step, we've tried to be calm and sensible about it, we've shouted, imposed rules and boundaries which seemed to help a bit for a while. Have we missed something? Don't know if we're being too strict or too soft with him. We try to make a fuss of him at the weekend and do special things with him but it's made no difference. Obviously we can't (or won't) ignore DS2 just to save DS1's hurt feelings but both feel at the end of our tether. Are we completely wrong and this has nothing to do with DS2, it's just the timing seems right to us.
Lastly I should mention his attitude is horrendous at times towards me. He's always been a daddy's boy, but when he's rude it's pretty much always towards me. Tells me to go and sit on another chair, or away from him and daddy. When I say hello or try and play with him he shouts NO! at me. Pushes me away when I try to hug him. Lots of "I want daddy!" There are many other instances I could mention but you get the picture. I feel my relationship with him is just going down the toilet and I just want to cry sometimes. I just can't work out if it's jealousy of DS2, or we just don't have a good enough relationship. Or a bit of both. When we do spend time together he can be quite lovely if we're on our own together of if DH is doing something with DS2. I then feel all optimistic till the whole bossy/shouty/angry/rejecting toddler appears again. Please help!
