Could she be any more comfortable?! Celeste is 16 months, 24lbs, 28in, and 12-18m fits her perfectly with room to grow! This fabric is SO soft!! It’s thicker and warmer than the regular bamboo sleepers, but still breathable so she’s not too hot when playing with her sister! This is a must have for these cold winter months, we will be wearing these to lounge, sleep, and play! They’re the perfect base layer for under snowsuits!
