It's definitely time to put away the fleece sleep sacks, but we still like to have a little something on the baby; if the windows are open, it may get cool or breezy, and if the AC is on, she may catch a chill. We were so happy to discover Aden + Anais, the maker of our favorite muslin blankets, also makes a sleep sack.
They come in two sizes up to 12 months and four different patterns. The muslin material is so soft- the swaddling blankets quickly became our daughter's favorite for nap times, but for nighttime sleeping, we need something that will actually stay on! Available here!
