Our center was just a hair over $300 per week per kid for infants. Goes down a bit as they get older.
Maybe I try to justify it to myself, but we have a friend paying a little more than half that at an in-home. It seems like they basically just watch TV all day and play the rest. Our kids could write their names by age 3, it seemed like.
Yeah, I noticed the same with my kid. They even have them picking up some "Sight" words.
