I always had to change Eleanor after a couple of hours as she would always leak and i would have to change everything. Not sure why it's bunching up in the middle.

The one thing i did do now and again was the hot wash with no powder in and then a hot wash with half powder then a cold rinse. Air dry them and then they would be okay. It all depends on how much powder you use with the peapods i found it was best not to use much at all as i think they seem to hold the powder more.
