For the last few weeks, ds has preferred to sleep on his side. Since that time, he has been waking up wet on the side he slept on. The diapers we use are Pampers Cruisers, size 3. I think that the pee is just coming right up his belly, and out of the diaper. I have tried switching diapers, and nothing is working. The diapers aren't even soaked when I change him, so I know it can absorb more, has anyone had this problem?
