I have a 14 week old who is a big lump- he's just gone into 6-9 month clothes and now he's beginning to grow out of his size 3 nappies. The trouble is that so far all I have found which will contain his very runny EBF poo has been newborn nappies with the mesh inside (I have only tried the Pampers brand so far) and they stop making them for babies this size. His poo just flows out of the legs and/or waist no matter what I do of the baby dry ones. I have nearly 3 months longer until solids which is a long time to have to wash his clothes every time he poos!
Any advice?
