Girls, if you crave the same dishes during your second pregnancy as with your first, is it really true that they will be same-sex children? The first time I craved only fruits, very indifferent to meat dishes, sometimes even felt sick from fatty and meaty dishes. This time it's happening again. We can't know the sex yet by ultrasound. But still, it's interesting) thanks
