Weehuggers covers before I saw one. I looked them up after seeing a bunch of rave reviews, and the first thing I noticed was the CUTE prints. Lots of great options for both boys and girls, and in both snaps and hook & loop.
I liked the idea of two sizes, as sometimes one size covers are too bulky on little babies and too small for my big boys.
I finally got to touch and feel them in the store, and grabbed a size 2 to try out on my kids. I first put it on my youngest, who is almost 18 months old and around 27lbs. An Econobum prefold fits very nicely folded inside. I was amazed that it was so roomy even at the top of the weight range.
I was so impressed, in fact, that I decided to try it on my older boy -- who is 3.5 years and almost 40lbs. I used a Babykicks hemp insert topped with a doubler, and was shocked that it was even roomy on him! The picture shows that even on a very large kid, there was still another set of snaps to use if necessary.
The double leg gussets provided great leak protection. Another unique feature is the flaps that hold inserts in place -- they are soft fabric against baby and PUL waterproof underneath so that no wetness seeps through.
Overall this is probably my favorite cover. The features plus the fit and prints make it a great choice.
