Went shopping (to one shop) with son who needed to try something on. He is nearly 5.5. He is not good at clothes/shoe shopping. Anyway I was a bit exasperatedly asking him to tell me if it was comfortable or not and out of the blue he hit me on the shoulder. Obviously just lost control. It is unusual for him to act like this, although not a complete first. He did apologise etc. I just wondered what mumsnet would think would have been the correct reaction from me? And also will he grow out of it or is the start of this behaviour?
