Can a type ab mother also have an ab child?

Why not? If a mother is type AB, it means she has A and B antigens in her and zero antibodies. If the father is type A, B, or AB, there is a chance that the child can be type AB. It all depends on luck. If the father is type A, and he happens to donate that antigen, and the mother happens to donate the B antigen in her body, then voila! Type AB. If the father is type B, and he happens to donate that antigen, and the mother happens to donate the A antigen in her body, then voila! Type AB. If the father is type AB, and he donates either. The child can be type AB as long as the mother donates the opposite one. It's really all chance. If you are asking whether the mother will reject the blood type in the child, then of course not. They are the same blood type. Perfectly compatible.
