Tell me about your baby's blood type. Girls, what is the sex of your child? Is there a stripe on their belly from bottom to top? For statistics? Also, if you have 1+ blood and your husband has 1+, what is the sex of the child diagnosed? It would be interesting to test this theory by looking at statistics! Write in the comments about your blood group and stripes, I'd like to hear it.
