If the child ends up with O+ blood and the mother is O-, there is a chance the mothers body will reject the baby and produce antibodies that attack it. There is a shot that prevents this from happening. Talk to your doctor... they will give you the best advice.

As far as I can remember, blood types being positive and negative does not tell i a blood type is an AO or BO. The blood types that you have given then could be AO positive and BO positive. If you will use a punnet square: .....A.... O B .AB.. BO O. AO .OO There is a possibility that one of their children will have the blood type O. However, the possibility of O being negative is quite rare, because both parents are positive.

Can parents with blood group o positive and a positive have child with a positive blood group?

yes, for the blood types there are 2 genes that decide ABO/+- the ABO is based on a gene with 3 genotypes, which are i, IA and IB if a person has ii, they have O blood, if they have iIA or IAIA they have A blood, if they have iIB or IBIB they have B blood and if they have IAIB they have AB blood positibe/negative is the rhesusfactor, it actually works with 3 genes(C, D, and E), but anything other than cde/cde will give rhesus-positive blood, so a parent with ii-cde/cde will have O-negative, and iIA/CDe/CDe will give A-positive, the only 2 blood-types the children can have with this set of parents are A-positive and O-positive
