DS2 is 5.5 months and has always had a magic ability to leak out of nappies - cloth, disposable, you name it, he's leaked out of it.
He was going through the night ok in a Moltex disposable, but for the last two weeks he's leaked every single night. Always up the side and up onto his back, never out of the legs.
He was near the top weight for the size he was in so I got some of the next size up and he's still leaking out of them. It's not an absorbency issue as the nappy isn't full by any means when he wakes up wet.
Any thoughts, tips, anyone had this experience? We're fixing the nappy on tight, pointing his willy downwards etc etc and yet he still manages to leak. We tried cloth at night but he was soaked really quickly (we use Fluffles and Motherease wraps) even with boosters etc, so we went back to disposables for nighttimes. He has to be kept as dry as possible as he has a big haemangioma (strawberry birthmark) on his groin which will ulcerate and scar if he gets nappy rash.
Please help, can't take the 4am nappy/babygro/sleeping bag change much longer, plus there's too much washing!
