This is my first time posting but I am at my wits end with my 2 year olds behaviour which seems to be getting worse daily. I had a new baby 3 months ago when my son was 22 months and he has not coped well at all. The baby has terrible reflux and colic so is very high needs which has made the adjustment more stressful for us all. My son is very rough with the baby hitting him, scratching, etc and I can not leave him unattended for a minute. His night time sleep is terrible and he is waking up multiple times a night crying to get into bed with his dad (he demands I leave the bed). We have stopped allowing him in as we were all exhausted but he still wakes up crying for his dad. He never wants me anymore and it is as if he has fallen out with me due to the arrival on the baby. He will hit me and lash out when I try to dress him, put on his clothes etc. I try so hard to spend 1:1 time and take him swimming and to a Gymboree class every week. His behaviour at nursery is also awful. Today he badly scratched a little girls face and I was in tears driving home as I felt so ashamed and like a terrible parent. The worst part is he shows no remorse and even after been told off and asked to apologies he runs back and does the same negative behaviour again. I have tried ignoring the behaviour, time out but seen little improvement. I also think part of the problem is sleep deprivation. He can be good and will sit a read his books or kiss the baby but it is few and far between. He goes to his grams one day a week and for some strange reason is always well behaved but turns into a monster the minute he walks in the front door. I really don't know if it is a phase or he has a behavioural issue that needs address. Any advice would be very much welcomed.
