My kids want to help but since they are 1 and 2 they don't get to do much more than watch. They love to touch them, and my oldest knows which snakes are albinos. I'm trying to teach her a few more simple morphs. My husband will hold "his" snake, but gets too antsy with my other snakes. He pays for feeders when I have to buy them. Also food for the rats I have but thats it. He won't help clean anyone out or feed them. I'm ok with that though. If we ever go on vacation My sister is comfortable enough with my snakes to keep watch over them for me. I don't think she would be ok with feeding them though. Not sure about taking care of the rats yet though.
On the other end of things are my mom and grandmother. Neither one gets why I like reptiles especially snakes. My grandmother is so scared of snakes that she can't even watch them on TV. I respect her feelings towards them and make sure they never cross paths. When I hosted thanksgiving one year I hid my snake where she wouldn't go and covered it's tank just for good measure. My mom makes it clear that she thinks they aren't safe to be around my kids. She still gives me crap about keeping snakes, and has made it clear that if for any reason we have to stay with her long term they are not welcome. I make it a point that if she starts asking questions she gets calm honest answers, but getting her to realize she has stepped over the line with careless comments is still a big issue.
