For us sposies always leak the worst. When we are away for the weekend or grandma's babysitting and the boys are wearing sposies, I can almost guarantee we will need a couple changes of clothes (perhaps for mom, dad and grandma as well).
A well-folded prefold and a great cover can almost always prevent poosplosions - the jelly roll fold is my favorite defense. Here's how you do it (please excuse the blurry pics):
Lay your beautiful babe on the diaper. This is my youngest son at about 11 wks. Pardon the wipe in the middle - that's merely for discretion. If you have extra length you need to fold down, I prefer to do it in the back before I start so the little fold acts as an extra poo barrier.
Roll the edges in toward the middle.
You want to roll the edges in enough so you can bring the diaper up between the legs.
Then pin or Snappi in place! The last thing I would do, not shown here, would be to make sure baby's legwarmers and shirt are not tucked into the diaper, or they will get all wet! Then I either put on a diaper cover or wool pants and we are good to go!
Like the leg warmers? They are pretty easy to make yourself if you have a sewing machine. Stay tuned to future posts!
