The babies don't usually develope sex until about 1 1/2 months, in my experience. Also, if the baby is too small (small enough to fit into dads mouth) then there is a good chance it will get eaten. Dieing from childbirth has never occured in my experience so I would not be too worried about that, but you may have a different problem all together. When the babies does develop sexual organs, males have a modified anal fin that is rounded and can be flexed in many directions. The female have a normal anal fin and show a dark spot where the eggs are. You can see pics of both male & female gups on my website www.winovichreptiles.com/aquatics.html Hope this helped!
