I'm o+, my husband is ab+. what's the likelihood of our baby having neonatal anemia? high risk pregnancy w/ maternal anemia and planned c-section cutting through anterior placenta previa.

Not likely: Even with your blood types as they are, this is very unlikely to effect the baby. This type of C section is higher risk, but don't worry,I have done it several times and I am sure that your doc will handle it fine if they are prepared.

Possible: There is some possibility of an A/O or B/O reaction with jaundice and hemolytic disease but that part of this is usually minor and easy to manage. An OB with quick hands can limit the other issue. I would try to relax and figure out what your life will be like with 3 kids running around.
