DS is 8 weeks, 6 kg and since birth all his nappies leak! All brands! I've tried Huggies, babylove, smugglers, woolies brand. The old Huggies leaked and the new design ones leak as well. They are leaking for wee up the sides where the taps cross over. He is a big boy...4.52kg birth weight I never had this issue with my other two, a DS who was also big and a DD. It is totally doing my head in.
