I've finally got my mattress for cot and bassinet, after buying the wrong size for both a few times :s grr, but now I need to know just how many mattress protectors people recommend I need? Just the one or mabey two? And also I live in Adelaide and am due in september so just wanting to know what adelaide mummies would use, cotton or flannelette for that time of year? And sheet wise too? Use cot sheets? Swaddle or wrap? What's the difference? Or sleeping bag? So many options! Help!
