The cotton fabric is sturdy and washes well on these Gerber Onesies.  I love them, but YOU MUST GET A SIZE UP from what your baby is currently wearing.  They run very small.  Getting one size up works nicely.

** ADDENDUM / OCT 2010 ** I wish I could take back at least one star.  While the original newborn and 3-6 month Gerber Onesies are great, the larger sized ones are not made well.  I recently purchased the 12 month size and noticed that the cotton was much thinner than the smaller sized ones and the snaps at the bottom do not snap well (some not at all).  One of them is even starting to tear a whole under one of the arms!

I noticed that the 12 month pack I purchased said "Made in India".  Don't know where the smaller ones were made or if Gerber just changed their manufacturer to go cheap.  The newest ones are not so hot.  You might be better off going with a different brand.
