Caring for children in other parents home....

[Play and Learn]

I had no kids of my own back then (only have one in my belly currently!) - and wasn't married yet! So I am not really sure!

IMO....if she won't take you without your kids, don't do it! As you stated before, you're doing this to stay with YOUR children!
What is the rate that they're offering you? Did they offer to feed your children while their children eat?
