Newborn blood types: Answer: all of them. A baby's blood may be different from the mother's blood (due to the father's contribution). In normal circumstances there is no problem. Rarely, some of the mother's antibodies, may leak into the baby/fetus' circulation and cause a reaction, usually minor (and treatable). The old worry about severe disease was the rh- blood type (rh - mom with an rh+ dad), now treatable.

I wouldn't sweat it: The era of worrying much about blood group problems has come & gone with the development of treatments for rh negative mothers that eliminate most major reactions. Abo issues remain, but are rarely very troublesome. Most kids with reactions have manageable jaundice that responds to simple treatments. I remember transfusing only 1 kid in 3 decades with an incompatibility rxn.
