My DD is in a great home daycare. I love that the DCP only takes babies/toddlers up to 2 1/2 (although I'm already dreading the though of DD having to leave her), she has 2 full-time helpers, so closing when DCP is sick is never an issue - she just stays upstairs & the helpers are there. Consistent care is another biggie, this DCP has been caring for babies for 18 years in her home. Her 2 helpers have been with her for awhile, one 7 years and the other 3 years. I love that there's no TV, no loud music or tons of screaming kids from other classes (like at a center), the place is calm-even with 8-9 babies/toddlers. They use positive, gentle discipline (& not that you need much discipline for toddlers anyway). I love that I know I can pop in anytime and I'm welcome and feel comfortable. I breastfed there every day for months & months during my lunch hour & that helped me feel so much better, too, cause I got to know them all pretty well & could see how they interact and really do care about the kids and give them all lots of love. They never let 'em CIO. They know how to handle breastmilk, They go by DD's schedule & never insist on her behaving any particular way and they ask lots of questions about what DD is used to, what she likes, what she responds to, how she falls asleep, what's she like when she wakes up, etc. It's just obvious that they care and are committed to providing quality day care that's as good for kids as a daycare can be & responsive to parents, too.
We asked around - we asked EVERYBODY and then we interviewed, checked references and sat around there a lot the first few weeks we left DD there.
Good luck, it's a tough thing!
