This shirt has some definite pros, but I think I'll stick with onesies.  I like the material - it's high quality and soft.  I also like the way it wraps around so that I don't have to pull the shirt over my son's head (which he hates).  However, with babies that are little (he's in 0-3 month) it rides up constantly.  I really dislike having to constantly pull the shirt down whenever I pick him up or move him.  If they had combined the onesie/wrap design it would be perfect.
