I'm a HUGE fan of daycare! Simon's been going since he was a baby and when I got Hallie I started taking her too so she could be more socialized (she was kept in a very small plastic kennel all day and night). I have been very lucky to have found really great places that I love. Here in NY I checked out a few places and finally decided on petspa b/c they had a 4 hour trial period that the dogs must pass before going. I interviewed them myself and asked a ton of questions to really get a feel for the place. I also get them groomed there and they really go above and beyond for me and the monkeys.
When you go visit you will very quickly get a feel if the place is right or not. Good Luck, your baby will love the playtime
