Years ago, when my kids were about 5, 7 and 8, we used whatever Disney called it then (LOL) for one night to have DH and I go out to dinner. I think I would feel comfortable leaving a baby if the baby were asleep and unlikely to wake up, but if there was a good chance he'd wake up, I wouldn't want him to wake up to find Mommy and Daddy gone and only a stranger there, especially because he's not in his own home, but at a hotel. I was probably over-protective of my kids when they were that small, though, and never left them with anyone other than a trusted adult who they knew very well. But that's me, and each person has to decide what's right for his/her own kids. You know your own child well enough to consider how he would react. I did trust Disney to provide qualified babysitters, though, so if you think your child would be OK with a babysitter, I wouldn't worry about the character of the babysitter.
