I made a pair of split croch pants for aowyn out of a sweater. That way she can go easily without taking undies on/off and she isn't cold! Here is the blog and tutorial where you can get the free pattern: http://doityourselfec.blogspot.com/2008/01/three-seam-split-crotch-pants.html?m=1

You can also use the elastic band to hold a prefold to catch accidents. 

I have never used these before so I will update when we determine how they work!
