Congratulations on your little present. It's such a bonding experience. As for the shedding. There have been people post about this before, so it's not completely uncommon. Really, the only thing I can think of that causes it is a growth spurt. Hopefully some of those who have experience with this will jump in...
If you aren't already doing it, it is a good idea to keep accurate records of your snakes feeding, defecation, shed and growth rates. That way you can have a clearer picture of your snakes tendencies and habits.
