Aden + Anais summer gauze sleep sacks, a set of two. I carefully selected these after reading books about sleep. I used them throughout the year, except in winter, as I adjusted the room temperature. The bamboo ones are thinner and have a smooth, silky feel like rayon. Pink: 12-18 months (botanical pattern) - bamboo White: 6-12 months (elephant pattern) - cotton Both were around 4000 yen each. I'd like to sell them as a set. I'm also selling other baby clothes and nursing wear from MOTHERS!
