To help ensure a restful night's sleep, bedding and sleepwear should be soft, warm and free of harmful chemicals. All our sleep products are made of 100% pure, untreated organic cotton. 
Federal regulations require that  sleepwear for children over the age of 9 months be tight fitting or be treated with (toxic) fire retardants. Our Long Johns collection comply with these  regulations because of their snug fit.
For over 50 years,  European parents have used  Sleep Bags to keep their little ones covered and warm at night.  Absurdly, they do not meet US sleepwear regulations and so we must recommend that you only use them for lounging. 
3 new shipments pajamas will arrive by November 1st.  Check back then for even more choices.
