We started CD a couple month ago and went with the FLIP system because my hubby liked the idea of reusing the covers. At first we didn't have any issues but now my son is soaking through his diapers after 1.5 hr. He is 17m. We are running out of clean pants!! We have tried extra rinses, washing without soap. He's ready to go back to disposables but we have another baby on the way and I would really like to stick with CD.
