Hi,i just started to use MMK CD three weeks ago,i prewashed several before i use them. But,they leaks! My boy prefers to sleep on tummy, everytime the pee makes his front part of his shirt wet! (that is just his first pee) When i checked on the CD,i realised the insert was dry, the layer hasnt absorb the pee before it leaked. So i dropped the water and tested. The dropplet still stay put on the layer,even though i use my finger to press it,it also cannot pass thru the layer.. Now how? I've been washing it for many times..yet it always leaks..

ps: i'm using nellie detergent,bought from MMK.
