Daycare decision?

My son will be 2 in less than a month. Our current babysitter is a relative, who we pay just like we would any other daycare provider. We love and trust this relative and we are very grateful she was able to watch him up until now. Here is the thing, I am feeling like my son now needs to be in an environment that teaches him. We try and work with him in the evenings, but I think it would be better if it was reinforced during the day as well. I found a daycare provider who not only watch kids, but educate them as well. Get this, for the same prie. My question is, knowing he is with family and safe is priceless, but so is education. Should I "can" the fam and go with the new provider?
