Blow Out

I was talking about diapers with some friends recently and talking about how sometimes they leak if they get too full or if it just isn't on right or something, and one of my friends mentioned something called a "blow out" and I don't think I fully understood until just recently...
I promise it had only been a couple of hours since we had last changed him, but this is what we found after taking his pants off the other day to change him...
Notice how far up the leg it goes...and how much of it is on the shirt...and imagine how much was on the pants that we took off!!
