I just want to say it sounds like you are being very responsible on the "kid" issue and it's so nice to see someone else who has the same views on it as I do
And yeah - I am of the same mind when it comes to my children, I never did the baby proofing thing and have some pretty well behaved kids (unless, of course, you ask my mother in law -- she thinks they should never talk! LOL)
The way I got my kids to make sure that EVERY little thing is picked up is by telling them that anything that is left on the floor belongs to Tia (my daughter had the unfortunate habit of leaving My Little Ponies and Care Bears around the house!) They very quickly learned to clean up those toys or they would be ruined incredibly quickly! Now I just need to get my husband to remember to pick up his socks!
It sounds like you have your ducks in a row here and it is really nice to see.
