I personally don't like popping at all but it is easier with babies. You will get pee'd on most likely from compressing the glands. You can also mis-sex this way if you do not use enough pressure and a rocking motion to get the "stuff" to pop out. Just enough pressure to get something out but not enough to hurt the snake. Problem is, baby males look alot like females at hatching since the hemi penes are not very long. Its best to have other snakes of similer age for comparison "pops" until you really know what you are looking for. Then when you see it you will know.
