Is your baby bi-racial? In 2001, my cousin was in prison and pregnant and we kept her baby for a few months until she was released. She met another woman in there who was also pregnant with no family and we kept her baby until she was released. Both babies were bi-racial. My husband has red hair and freckles and I have brown hair and fair skin and I got alot of those kind of questions (living in the south, some of them weren't so friendly. Alot of people here still have problems with bi-racial babies. Go figure!
) One of the boys, Jeremy, looked much more AA than Micah did. People thought they were twins and did have questions. With Jeremy, his father is unknown and Micah does look like his dad. I'd tell people that Jeremy looked like his mom and Micah like his dad. They would give strange looks, but I didn't feel like I owed them any explanation, and you don't either. If you know that one bparent had curly hair, then say he gets it from his "dad" and keep going.
Good luck,
Jill
