"expensive toys" I don't know why I spent any $$$ at all on my DS. If he plays with the television one more time, ahhhhh. You just have to watch, there will be bruises, tumbles etc & lots of cuddles. Charlie had a whopper at the play cafe the other day & has already split his lip & that was only a day or 2 after starting to crawl.
I have packed away all dangerous stuff etc, but haven't gone too nuts. I think they also need to learn "no", especially when you go to someone elses house as they are not always babyproof.
