Dd has just turned 4 and for the last six months or so has been really hard work. She’s always been strong willed but now she’s become v hard work. If she gets upset about something, she hits and kicks and screams and cries, it’s getting to the point that Dh and I are finding it hard to cope with and are walking on eggshells. She wasn’t like this until around 3, when she got a little harder, but nothing like the last 6 months or so. I assumed she’d get easier or at least not be kicking, hitting and sometimes biting, is this normal behaviour, no idea what to do, she starts school in September and so worried how she’ll be.
