Family Addition?

We've been tossing around getting a pet for the kids lately. Well, it would have to be two because the girls really just cannot share. There are a lot of things to weigh out when making this kind of decision, mostly what we will do when we have to travel, not to mention what kind of pets to get. I'm partial to smaller animals just because they are a little easier to deal with, but they aren't quite kid-friendly unless it was a rabbit. We do love rabbits but we would have to worry about making the house safe for it to go around. We would need to cover everything in a cable protector because we have so many loose wires and cords, we would have to be able to put everything on the floor away, and so on and so on. I'm not sure if it's really a great idea right now, but maybe once we figure things out we can make a solid decision.
