We've used Gerber and JC Penney. You can buy the Gerber ones at Target and Wal-Mart usually near the toddler underwear and layette stuff. I've found the JC Penny kind to be slightly more absorbent and less binding on my son's legs. They're by the baby undershirts/onesies etc. I wash them in with regular clothes but dry them without fabric softener to keep them more absorbent. If you run a little vinegar in the final rinse cycle it keeps them from getting too stiff.
