My mother was a preschool teacher, mostly in daycare settings when she worked for someone else. She also did a preschool in our home for a while when I was growing up. After talking to her about the differences, if I had to choose, I would put my child in an at home daycare. The fancy, expensive "structured" daycares hardly ever get to give those little ones the individual attention that they need. At age two, they don't need a bunch of fancy activities, they need love and room to explore. You are more likely to get this at an in home child care. Just do your research and pick a place that you and your son are both comfortable with. Ask them about what their day is like, and if you can, take the time to observe.
