Blood type inheritance is pretty well worked out. What we're talking about when we talk about the type is whether your red blood cells have certain markers on them. There are only two kinds: the A and the B. We use O as a place-holder (like a zero) for someone who doesn't have either A or B.
Everyone has two genes for letter blood type. But since mom is type O, we know she's got no A's or B's and only O genes. Dad is type A, so at least one of his genes is an A gene. The other one could be either another A or an O.
Since children get one gene for this from mom and one from Dad, you can see that there's really only two possible choices for the baby: it always get an O from mom (that's all she has), and it could get an A from Dad, or possibly another O if he has one. Baby can only be OA = type A or OO = type O. Type B is RIGHT OUT.
Sorry.

I think that the mother and child have the same blood type. My daughter and I both have B+.

No, as the mother is 00 and the father is A0, so no B to express.

Definitely not.
Mother is O+, which has OO
Father is A-, which has AO
A mix/cross only gives, OO (ie O) or AO (ie A).
