hi my 3 year old whos at nursery am and starts full time school in sept has become a nightmare! when i had his little bro in oct he loved him but now never leaves the baby alone, he wakes him up trys to hurt him and just bugs him all the time, his behaviour has got worse (he has never been a angel!) everything is a battle, he wont do as he is told and if you say no screams, hits, and shouts to get his own way. doesnt matter where we are school, asda etc. ive tried timeout, reward charts, taking toys away. can anyone offer any advice cos its really geeting me down
