Selecting gender is illegal and biologically impossible naturally. If you want twins, sometimes fertility treatments can increase the chances, but please discuss this safely with your gynac.
Actually, I also read about this, but medically we cannot choose the gender of the baby. Having a healthy child, boy or girl, is the biggest blessing, na?
Haha, carrying even one baby till the 3rd trimester is a huge task, imagine twins! There is no trick to choose the gender or have twins, just pray for a healthy delivery!
Honestly, there is no way to choose the gender or guarantee twins, it's all natural. Focus on your health, eat balanced meals, and let nature do its work.
My family also wanted a boy and twins, but honestly, it's not in our hands. As long as the baby is healthy, that's all that matters. Don't fall for any fake home remedies.
