I'm confused when people say that in home care gets insepected less often than centers. If you go the dfps website, you'll see that's simply not true (unless you're sending your child to a registered or listed in home place). My son's previous LICENSED in home center is inspected at the same frequency as his preschool.
My son's in home center taught him sign language, the babies had their own space completely separate from the walkers/young toddlers (it's a husband/wife combo with a PT assistant), they don't keep toddlers past the age of 3, their house is spotless clean and MUCH quieter than a center, the toddlers had a great educational curriculum, etc, etc, etc.
The high quality, licensed in home providers (in my opinion) provide better, more consistent care for infants and young toddlers. You don't have to worry about turnover, you don't have to worry about telling the morning person a particular thing and then wonder if they're going to tell the afternoon person, etc, etc. If you pick THE RIGHT in home center, your infant won't be in the same space as a 4 year old. If you pick THE RIGHT in home center, you won't have all the complaints that people here have against in home places.
Once a toddler reaches 2.5-3, I think a high quality preschool is better. When my son was at his in home center, he was the oldest and only one potty training. Moving him to preschool sped up potty training and helped him learn more from the older 2s and 3s in his class.
The most important part of this equation is HIGH QUALITY. There are cruddy in home places and there are cruddy centers. You get what you put into it. So, if you don't research and visit and do ALL your homework, of course you're going to find yourself at a bad place, whether it's in home or at a center.
