My Costco has 100% Organic Cotton Kid Pajamas (Hanna Andersson brand) without flame retardant...for $11.99!
Google wouldn't let me upload any pics...but they are great!
They are thicker, sturdy cotton, without feet (Great for Tucson Summers). It looked like they go up to size 3.
There were some really cute pink ones, but alas, I opted for the less cute boy-ish ones in every size...hoping they will last through, at least, one more kid.
