Tim (Dad), Kayli (Mom), Marty (22 month old son). We've got a big dog, a small dog, and 2 cats. I don't mean to brag, but Marty is pretty perfect. The daycare loves him and calls him "the happy baby". He'll take some time to get warmed up to you, but will basically be no trouble at all.
Honestly, we just need a warm body in the house while he's sleeping. Nothing super intensive, maybe if it's early enough in the evening; feed him, change him, read to him, and then put him down for bed.
Schedule: We're looking for one night a week. He might even be asleep when you arrive. Occasionally weekends during the day into the night.
