We have liked the quality and value of aldi nappies, but they occaisionaly leaked up the bac, so we moved into the bgger size and it was fine for a while, but now we are getting regular leaks again. DS is too small to go into a bigger nappy, and often the leak occurs when the nappy is not even very full. It always leaks in the same place, on the back left side. It happens when he is lying down. Usually when he is asleep. I try to be careful to put the on properly. It doesnt happen every time, but over last night we had 3 leaks!

Any tips? what other brands might we want to try?
