I got these as a gift for my baby shower. My brother loves these diapers on my nephew, so he figured I would like them too. I guess it is different for every baby as their bodies are shaped differently but these did not fit my 3 month old daughter at all. I will not purchase them again for her. They did not rise up the back far enough so she had some explosions up her back, and she always leaked out of the legs. They also did not seem to be comfortable for her, it seemed like they fit very oddly around her legs. She does not have very fat legs but they were tighter around her legs. I notice she was very fussy while wearing these diapers and I am wondering if it has to do with the fit. Every day she would leak out all over her clothes, which ruined some of her white clothes almost beyond repair. I'm not sure if it has to do with the fact she is a girl, but the fit of these diapers was not good at all.
If she soiled in these diapers I would have to change them immediately to avoid a blow out.
I also noticed that the diaper is just square shaped when you open it, it does not seem to conform to the body well enough. There are no guards around the legs like most other diapers have, they also feel very thick - which feels like a good thing at first but it seems to me they are thick for no reason.
The price is very reasonable, so you should give it a try if you don't mind the possible disappointment. My brother loves these diapers, but I don't. They could fit your baby better than mine - possibly they fit boys better than girls.
