My 3 year old boys behaviour has gone crazy. He was so excited about baby, and when baby arrived he was so kind and caring it melted our hearts. 1 week in and that’s all changed. At bed times, our eldest turns into an absolute nightmare- hours screaming, hitting, kicking and constantly testing to see what he can get away with. We’ve tried gentle parenting ( what we normally follow) but the tantrums are so extreme and long it’s not possible to just wait it out when we have a newborn waiting in a bath, feeds and bed too. It’s always around bedtime and the other night he even woke screaming he hated me and our baby and wanted us downstairs. We’ve tried keeping the routine as it was before baby but our eldest is refusing that too and demands different things several times a night until eventually he just goes to sleep. We’ve also tried the strict approach but that enraged him and it just lasts longer and longer. He says a lot he doesn’t want me anymore which is really hard to hear. I got severe post natal after him and medicated to keep on top of it and work hard to build a really strong bond with him. I feel like overnight it’s all ruined. In the day he is adorable with our newborn and kind and caring. We shower him with attention to try and ease him into being a big brother and help him feel secure but it’s not making any difference to the night time. Help - any others like this? What did you do? I was expecting something but not to this severity. I’m running out of ideas and I’m getting down about it.
