I'm absolutely at the end of my tether. Nearly 4 yr old bites, kicks, hits, intentionally disobedient. Today we'd been out for 5 minutes 3 tantrums including 1 because he wanted to run across a car park alone. He won't walk anywhere, he frequently hurts me intentionally whole laughing. He tantrums all.the.time. no matter how much sleep or food. A few minutes ago he ran out of the house down the street. I am on the edge completely I've no idea how other people cope I do not enjoy being a mother anymore even a short trip to the corner shop is intolerable.
