Toddler is 2 years 9 months and his new sister is 6 weeks. So it’s early days, but he’s just being awful. He tries to kick her, head butt her and uses objects to hit her with. He laughs when told not to. The only thing that has any effect is a time out in his bedroom but although this has an effect it’s very temporary and he starts the horrible behaviour again. He also deliberately wakes her if she’s sleeping. It makes days very stressful as I struggle to even go to the toilet.
I thought we’d prepared him for her arrival but I don’t know if we didn’t do something very well or if it’s just normal though upsetting. Any advice?
