My 2.3 year old is full of energy and very active. He is endlessly inventive in the trouble he gets into, including dangerous things like jumping on glass tables, throwing glass jars on the floor hard and hitting various items together. The problem is that saying 'no' even very firmly and followed directly by action (i.e. stopping him) only seems to encourage him. When I say 'no', his face lights up and he starts doing whatever he was doing at twice the speed. I stop him from doing it, remove him, he usually smiles as I tell him off, and then five minutes later he's doing it again.
I am not sure whether I am just encouraging bad behaviour by doing something he obviously finds reinforcing and whether I should start ignoring instead? My FIL helpfully said (after shouting at him) 'he needs to know that no means no' and I would agree, but how can I teach him that? Anyone else been in similar situation?
