I'm EBF and my baby has taken to holding the poop for a while and then letting loose an explosion.

For anyone in a similar boat - what kind of diapers do you use? Do you have issues with poop leaking? I'm currently using a mix of BG 4.0, BG Elementals, and prefolds with thirsties or flip covers. Poop seems to seep out around the legs (and my baby has chubby thighs!) no matter what I do.
It's a boy! Born 42 weeks, 2 days.

how do you use the prefolds? Do you fold them any particular way or use a snappi? I've just been laying mine in the cover . . . maybe that's part of the issue?
I use the angel wing fold when I use prefolds. It traps the poo rather nicely.
