How does one go about finding these? I've seen them mentioned as a way to occasionally enjoy a night out without the baby. We have an 8 month old and would be delighted to watch a few other littles in exchange for getting out ourselves once a month, but none of the other parents we know seem to do this kind of thing or be willing to entertain the idea (high COL area, most have nannies who babysit extra if needed, etc). Anyone know where to look? May also be a way to meet like minded other parents :)
