Nope, not at all. For two reasons: At conception, the DNA of the child is pretty much set. Lots of genes are activated and deactivated, but the genes themselves are unchanged. Think of it as one of those giant scrolling light-up signs. The lights turn on and off to display words and shapes, but the lightbulbs themselves don't change.
Second, there's normally no blood exchange between mother and child. In the placenta, the mother's blood passes close to the child's and delivers nutrients to the child, while taking away waste. The mother's blood never actually enters the child.
If the transfused blood was contaminated with a disease, it could pass through the thin barrier in the placenta into the child, but that wouldn't alter DNA.

No. The blood is determined at conception, I think.
