Ayja gets like that, she's like a little puppy, she gets all excited and nippy, lol. although with her, it seems to be when she has teeth coming through she bites anyone and everything in sight, her blankets, toys, cups, the chairs etc.. she actually did this tonight (she has all 4 eye teeth coming through currently), i saw her heading towards paris's arm with mouth wide open, paris managed to grab her arm away and ayja lunged again and again in the time it took me to get over there and stop her (cos my telling offs from the kitchen hadn't worked) she had managed to make a tidy red bite mark on Paris's arm.
Usually after a couple of minutes in time out it takes Paris to go over and show ayja what she did, that shocks ayja into thinking "oh my god" and she does the sorry thing without too much prompting.
But, yes biting is naughty and it hurts kids., but how about instead of focusing on the "that's naughty," stuff, encourage him to find other strategies.. ie, whether he's getting excited and silly, or getting grumpy in a tiz cos some kids doing something that's annoying or whatever.. encourage him to use his words. Remind him as often as you can, remind him he can come to you if there is something bad going on, even just teach him to "STOP" at the top of his lungs. as for being excited, teach him other ways, when he's excited he could hug the child or do something else.
Sometimes it takes a bit of reverse programming, focus on teaching new behaviours when the telling-off doesn't stop the undesirable ones.
also, if it happens soely at the playgroup it could be the attention maybe? so telling him off .. is attention, hence the thinking it s a great joke, he's thinking "HA i got her to stop what she was doing" in a round-about way. Try doing the hallway thing without talking to him, be firm, put him there, and that's it, when you go back talk to him, but at the time you need to show him that's not the way to get your attention. I usually tell the girls that too after the time oue, that's not the way to get my attention, that they could do X or X or X that would get them nice attention which is much much better.
hope some of that helps and doesn't just sound like a load of bull.
