Reviews

Cute, affordable & durable

"My boys love to match their Jammie’s, but that can get expensive. I appreciate Burt’s bees for having affordable pj’s that are durable (my four year old puts holes in all his pj’s but the Burt’s bees ones have not had that issue!) and a wide range of sizes so that they can all match!"

Lexie J. (5/5)

The only clothes a newborn needs

"My two and a-half-month old has lived in Burt’s Bees pajamas since she was born. They check every box for me: organic cotton, well made, two-way zippers, adorable prints. No other brand came close to the perfection of these onesies, including the more expensive ones. She went from newborn size to 0-3; when she outgrows these, I’ll size her up again in Burt’s. Note to the manufacturer: please make the yogi elephants print in the 6 month size!!"
