Here is closer look into Everson’s crib! We love our Newton Baby Mattress not only because it’s 100% breathable, but because you can also take it apart and wash the cover and the mattress! According to Newton Baby, you may use 100% Muslin Cotton Sheets to keep it 100% breathable. We also love his weighted sleep sack, it has definitely helped him sleep better. And can’t forget his favorite pacis!!
