How do they know to hold on to the pooey nappy bit until after you change them to a new nappy because of a wet nappy after waking up for a feed? DS's done this the last 3 days during the day when using MCNs and not when using sposies overnight Have worked out though to make sure there's no leg gape - got a wee bath on me, the feeding pillow and chair earlier today when he decided to wee while feeding. Noice! discovered afterwards that the side that leaked had some gape-age there.
