Try folding down the excess in the back, instead of the front. So, fold down 3 inches (or whatever you usually fold down in the front) and put baby on the diaper. When he's lying on the diaper try doing the
"twist" fold. Twist the diaper above his boy parts (that's the technical term we use in this house
) so that nothing falls out. So, for a girl the twist might be between her legs, but for a boy it should be a little higher. You might have to practice a few times before you get it good
Good luck!
