I believe it's in your legal limits... what you really have to ask yourself is... "Is it in my SANITY limits? " LOL

I have a before after hitting 10 in the fall. I've replaced her space and will be doing 5 plus her. I figure now she's like an apprentice. Very helpful. If you can get the right 10 year old it's easy money. And always nice to have someone to play a board game with or a hand of cards with during quiet time.
