Not again!

OOOOps! She did it again! (And all we could do was laugh!) Not sure what's up, but for the third time in as many days, Ysabella has managed to poop through her diaper! (and clothes, and blankets...) And she does it quietly at that. Sneaky little girl. Needless to say, she went right into the tub. Does anybody have any advice on what diapers are good to help prevent these spill-overs? We've been using Pampers, but obviously they're not working too well...this is getting to be way too tiresome and too much of a regular occurence.

P.S. I thought I'd use this colour font to match the poop. HA!
