I'm the only one of my female friends that doesn't have a child. I'm the resident babysitter for all of them. None of them mind that I have snakes (2 boas, 2 carpet pythons, 9 BPs and a pueblan milksnake). A few of them have actually started bringing over THEIR other friends with their kids so that they can go to the "Zoo".
If I ever have a child - I will always keep my pets. We already have pretty strict rules regarding the snakes and the kids, that'll just continue into day to day activities. I feel it is a spectacular way to introduce children to the fact that all animals are deserving of our love, not just the fuzzy ones.
