Baby deer born in our back yard

In June I was looking at some tadpoles in my backyard that hatched out of some eggs, and I put them in a bucket. Next to the bucket, I found a newborn baby deer and I was about 2 feet away from it. I fed it some blueberries. I also saw it eat them. I saw it stand up for its first time. It was wobbly. Then we went to my uncle Kevin's soccer game, and when we came back it was gone. Since then we have seen it around the neighborhood with its mom. Its getting bigger and bigger. Its losing its spots, and its fur is thicker. I was in my friend's yard when it came out of the bushes with its mom, about 10 feet away from me. I saw it eating plants and berries. It looked right at me.
