I have a bunch of gnappies that my sister was able to get a little more cheaply for me in the U.S (lucky me!). They are really cute, easy to use and a great fit however I am not finding them very absorbent at all. I'm new to the whole re-uable thing, but want to give it a good go. However I am currently changing every 1.5/2hrs! Has anyone else has this difficulty? Should I put another lining in, if so whats more absorbent? Is my babe (20wks) just a mammoth wee-er?
