My son is 3.5 and I have noticed in the last few months that he gets very silly when other children are around - it's usually when people come to our house or if we're out in a social situation. A friend of mine called in last night with her two daughters (aged 12 and 7), and ds proceeded to 'put on an act' for them, pretending to fall on the floor and jumping up and down in front of them, etc etc. He also doesn't listen to anything I say when he gets excited like this. I saw the girls rolling their eyes at him a few times, as though he was being totally irritating (which he probably was!)
Is this 'showing off' behaviour quite typical for kids his age, or is it major attention seeking? I can't say that I've noticed a lot of other children doing it, but that's probably because they're not my children so I don't tend to take much notice. Thanks..
