My daughter is 5, turns 6 in August, about a year ago she seems to have just changed, she used to be lovely, eat her dinner nicely, sit and watch a film together nicely, cuddle and just had really good listening skills, thus carried on to when she was at nursery as well. However she is now very badly behaved almost all the time. My partner and I have since had another baby but she didn't change once he was born it was a while after that it happened. She answers back all the time when I'm telling her off for something or she won't even listen at all and sits there just laughing over the top of me or dad talking. She sits talking all the way through dinner and just doesn't eat anything, if she's sent to her room for being naughty or rude she plays in the bathroom or just stomps her feet on the floor. We have tried many different things to stop these things happening but nothing seems to work. I give her 2 warnings before implementing punishments and always follow through with them. I've taken away favourite toys, I've stopped giving all sweets and treats if she's not good enough, no tv/tablet for bad behaviour, we've tried giving her 1 on 1 attention with just me and her and dad and her, dad took her to the park the other day just the two of them, she behaved well while there but since getting back home the following days she's just behaved worse. We both love her to bits but the relentless bad behaviour is becoming very difficult. Is it just her age and a stage she's going through or is there anything else anyone could suggest might be causing this and any advice on how to get her to behave better would be greatly appreciated! I am planning in the next week to get her a rewards chart and some stickers but I'm doubtful it will work!
