My DS is 9 months old, pre-verbal, just a little baby really. But I need to start saying 'no' in such a way that he'll listen - particularly when it comes to things that are dangerous. He's walking now and grabbing for everything (hot, sharp, or electrical things are preferred!). He's also decided that he doesn't like having his nappy changed and wriggles or crawls off.
When I say 'NO', he laughs. When I say 'No' in a serious voice, and get down to his level like Supernanny, he laughs uproariously. Then he goes back to what he was doing and as far as he's concerned it's turned into a bit of a game. When I pick him up & take him away from what he was doing it rewards him and so he goes straight back to the fragile/dangerous thing he was after because he wants to get picked up again. What do I do???
