Have 2.5 year old & 4 week old, older child now being so naughty & i don't know how to deal with it, got so upset yesterday as realised I'd done nothing but shout at him & give him a hard time. I know baby has shaken his world but don't know how to make it better, tried spending time alone, lots of cuddles, positive reinforcement etc but doesn't make much difference, or he just wants his dad who seems to be current favourite!
