Second baby, trialled them months ago on my toddler and happy with them. I've tried them today on my 2 month old but don't know if I was supposed to wash them to prepare?! I just put them straight on with fleece liner and disposable one. But it was very damp quickly and leaked within 2 hours? Probably completely wrong but as its Xmas I can't get hold of lady I bought them from and am getting confused on google! Thanks!
