Question

I'm a bit confused about my baby's blood group. My husband has a B blood group and mine is A, but somehow our baby's blood group is O. Could you help me understand why this might be? Is it something I should be worried about?

Question

I'm really confused and a bit worried about my child's blood group. My wife has O, mine is B, but our child's blood group came out as A. We've done the tests twice at a lab, and there's no mistake with the blood group results. Is it possible for our child to have this blood group combination? Could this mean anything serious or indicate that the child might be someone else's? I've read some articles that suggest a DNA test, but I'm not exactly sure what test to ask for at the lab. Should we be consulting a specific type of doctor for this issue? Any guidance would really help clear things up.

Question

I'm really worried about my 3-year-old. He's not walking or talking yet. We've already seen a neurological pediatrician who gave us Normabrain syrup, and we've done MRI, TMS, and some blood tests, but everything came back normal. We're planning to see a genetics specialist soon. Why hasn't he started walking yet? He can walk for about 5 to 6 feet before he falls down. Could there be an issue because I married my maternal uncle's daughter?
