DS's behaviour has been pretty rubbish since Dd was born 18months ago.
I've read up on strategies, I'm generally consistent, DH keeps suggesting that there's 'something wrong' but it seems unlikely as he is also able to control his behaviour and he was fantastic before DD arrived (he was nearly 3).
But at the moment I am utterly worn down by it. I am crying as I type, today I feel like a shit parent, I've just shouted and generally let go of all the strategies I've been trying to follow. I give him plenty of love, we have one on one time, he responds well to this and behaviour is definitely worse when DD is around. He's also not impressing them at school at the moment and it was the same at nursery. Again, this is only since DD.
I'm just so sad and don't really know where to go with him. I love him so much but I am so tired. DD is also a strong willed little thing but I feel that I am managing her whereas I don't feel that DS's behaviour is improving at all.
How much whiny/annoying/naughty behaviour is normal at this stage? Any ideas/shared experiences would be very welcome because I feel very low about it all day.
