How much does your pull up hold???

I am usually pretty good about doing laundry and make sure things dont get into the laundry basket that shouldnt be there, but lately Sarah is giving me a run for my money. Lately during quiet time aka nap time she has taken to going in her pull up and then discarding the pull up and changing herself. Yeah great times. Let me tell you, if I didnt hate doing laundry before, I despise it now. Today I accidently let a pull up get by me and it ended up in the washer. Let me tell you - if you never have checked them out, the Target brand pull ups rock! I took it out of the washer still in tact! And it was holding a ton of water! So it begs the question- how much does your pull up hold?
