We've tried several brands of bodysuits, and much to my surprise, these Disney ones are the best.  These are a medium-weight fabric- not paper thin like some others- and very soft. So far they have held up superbly to blowouts and multiple washings.  The "grow an inch" feature with two sets of snaps doubles the life of these.  Start on the first set of snaps, boom- growth spurt, no need to go buy more.  Just use the second set of snaps.  I wish I could go back in time and buy only these from the beginning.  I'll be getting them in the next size up.
