Babysitters or day care? Which one in better for your kid?

I actually placed a deposit in infant care for my daughter, but my father has expressed his willingness to look after my daughter for as long as I require. I've just placed her on the waiting list for the toddler class in another child care nearer to my house which starts at 18 months. The main reason is because at 18 months, she should be able to express herself and I'll know if she is being mistreated. I was taken care of by a babysitter until I was 3 years old, but I would prefer to place my child in infant care. This is because there is a curriculum and structure and my child will be able to interact with many peers her age. It will help to develop her social skills. Also, most babysitters end up placing the child in front of the television when they run out of activities to do.
