I personally think that both options have good and bad things about it. My advice is to really look at your priorities and figur out what will work best for you and your family. Home daycare is great that you get attention when you have an infant, however I have both my kids at a center as well and I'm completely happy with the set up. My son is 2 years old and he's at the age where interaction with older children helps him develope much faster. I am given a monthly schedule of things he is learning so I'm satsified that he is learning something everyday. The teachers are required to attend a professional training class periodically and so I'm guaranteed that they care continuously updated on teaching skills and emergency sisuations. They are a fully licensed center registered with the Better Business Bureau so any complaints against the center is publicly recorded. And lastly, there is control over who has access to my children - something that you have no control over at a home daycare. The center is open (there is only one room - for the infants) and no child is ever left alone with any adult at any given time. This defined my decision to go with the center with no regrets. We go to Kindercare. It is a chain of centers that is part of a large corporation so they are very accountable for their teachers.
You can tell I'm a little biased on my thoughts, but good luck and do some research. You may get a list of recommended care givers from your local community, church groups etc.
