Ok I'm at the end of my tether with my newly 3 year old and really need some help. I have a new baby and DS1's behaviour during my pregnancy and since has been awful, until then he was a mostly well behaved boy with just the occasional moment of naughtiness.
He loves being a brother and likes to "help" with the baby. We include him where possible and I always chat to him and play with him where possible while breastfeeding. Baby hasn't really been able to be put down this week so that hasn't helped.
DS1 has been toilet trained for months during the day but now screams and tantrums if we ask if he needs a wee or suggest he tries for a wee. At nursery he goes like a dream, tells them he needs to go or goes when asked, no fuss and does it all himself. If we get him to use the toilet at home, he insists he can't do it himself which makes it harder while feeding baby. He continually wets himself now and doesn't even mention it, is totally unfazed by having to get changed. We've tried stickers and praise and not really mentioning the accidents but no improvement.
We've reached a point where he now descends into bad behaviour when you ask him to use the toilet or if he wants to go. He screams and shouts, throws things and hits sometimes. We've tried ignoring the behaviour (shouting etc) or time out (hitting) but ignoring ramps things up to hitting and time outs he finds funny and just comes back so it's a game to put him back there or else they have no consequence - if he stays in time out, he's totally calm then when he gets brought back in, he immediately hits again.
I know it's attention but we're giving him loads and I just don't know what else to do. Please be nice because I know I'm failing and I just want to cry for my usually lovely little boy. Does anyone know how to prevent this behaviour or what method of discipline is best?
