My 3 year old son is being unbearable... lots of biting and general agression towards his younger brother (22 months) and lots of growling, whingeing at everyone else.
He seems to constantly do things he knows he shouldn't, we have to ask him to do/not do things a gazillion times. We are staying at my mother-in-law's and he has had lots of attention etc, sleeping and eating fine. He does seem worse than usual right now, but then a lot of this happens at home too so I have been getting concerned that he may be in an aggressive pattern of behaviour.
Is this the sort of thing that just resolves itself in time or should we be concerned?
Time out doesn't work because his little brother thinks its funny, reward charts seem to work a bit but as soon as they stop, the behaviour reverts. Is there any sort of 'punishment' is appropriate and does it even work for this agegroup??
