As the title says really. I’ve hit breaking point today and just feel defeated, I ended up in tears. Since he turned 2 his behaviour has just took a turn, hurting his siblings and we did have a new baby in December so I think partly could be jealousy. He dotes on his new baby brother but has started to try hitting him. He is just too heavy hands with him. He was breastfed but self weaned after his brother was born, I would have continued to breastfeed him but I always let my children self wean. today he bit his older brother on his thigh which has made quite the mark. I broke and shouted at him, told him it was naughty and took him upstairs to bed. But he just laughed. I kept repeating no. I just don’t know what I’m doing wrong. He laughs when I tell him off or sometimes just goes quiet and looks at me out the corner of his eyes. I know it’s probably very common, I just don’t know how to handle this phase as every day I’m getting more and more stressed out with his behaviour. He doesn’t attend any nursery btw and he is nice with other children but in the home and with his siblings he can be so difficult. Screaming because he knows it triggers his older brother, hitting, biting. What has worked for any of you that have been through similar?
