- we hardly baby-proofed anything - we would tell them that they couldn't touch something and explain why and they would listen even at 6 months old (we ended up having to do some babyproofing for visitors)
that was my boy, too. we had a couple playdates with other kids which were a bit eventful because of it. and more than once were accused of negligent parenting because people didn't believe a baby understood and complied with, "Don't touch. You'll get hurt."
we're also lucky to have a number of teachers as friends who confirmed our suspicions. one of them would babysit him sometimes. one time, when we got home to free her from his clutches, she just gave me this squinty-eyed LOOK. "Do you know your son knows the word 'buoyancy'?" they'd been playing with a toy boat in the sink, and she'd asked him if he knew why it didn't sink. he told her it was buoyant because it had air in it and because it's shape. he was 2 or so. we didn't see it as a big deal, but she insisted that this was not "normal" knowledge at his age. we took her word for it and just kept doing what we were doing.
