Any idea of how my husband and I can conceive a BABY GIRL next time????

Cassiee • Hello fabulous moms to be💕
After I give birth in October 10th and once this baby is 2yrs old my husband and u wants to try for a girl, but this time we will be going through our doctors to MAKE SURE we have twin baby girls. I don't believe we can do it on our own cause I feel as if his y chromosome is VERY STRONG or the counts are VERY HIGH.
