After three months of using cloth with no leak issues, we have had two in 24hours! We are getting leaks out of the back, waist part of the diaper. I'm not sure what we are doing wrong. Does this sound like we need the large insert instead of the newborn one, or is it something else completely?. Both times this happened, my husband was the one who diapered her, so I suppose he could have done something wrong. We use pocket diapers, and my baby is 12 weeks (11 pounds). Thanks!
