The Newborn insert works as an overnight booster for older babies or as extra absorbency for heavy wetters. Convienently packaged 6 to a pack.
I bought a set of these when my son was 4 months old to help us get through the night. Man what a difference!! Just one added to the normal os insert and no leaks any more at night!! I can't wait to try them on our newborn!! They slim down the diapers so much compaired to the OS. The only bad thing is that I have noticed you have to strip them on a more regular basis as they do start to stink after a while of heavy wetting.
I don't like the way these fit into my 4.0s and they're very rough compared to everything else in my stash. Plus for a 3 month old I have to use 2 if she's even going to take a nap while a prefold (not even in a trifold) can last her through the entire night.
Be careful when you buy these. They are not the bumGenius stay dry doubler!!!! I had previously purchased the bumGenius stay dry doublers (that came in packs of 3) that could be used as newborn inserts. I wanted to buy more, so I went to the bumGenius products & purchased these only to find out they are not the same item. These are advertised with nearly identical wording, are the same size & used for the same purpose, but ARE NOT the same items. I intially thought that I was sent the wrong item, so I e-mailed customer service. That was when I was told I had previously purchased the stay dry doubler, not the diaper doubler. I was told I could return them, but by the time I pay for shipping it wouldn't be worth it. Also, I have searched for the "stay dry doublers" on this website now & could not find them anywhere. So if have previously purchased the doublers & are looking to buy more, be aware these are not the same product.
These inserts are very absorbent, as advertised, and will deliver on all their claims. However I have stopped using them for several reasons: 1) they get smelly much quicker than my cotton fibers and made my nighttime diapers stink 2) the material does not feel good to my hands and clings to everything-it does not stay soft at all once washed 3) it is a material that cannot be against my son's skin, so I always had to be aware of that when diapering 4) it is white which I hated having mixed in with my natural stash-this is a purely cosmetic reason :) Overall, I have found an all cotton stash to be preferable. That is one woman's opinion, but I just sold these off and will be ordering hemp inserts in the case that I miss having a doubler.
I like these! I used one newborn insert in BG diapers from 1 month until 3 months, and then from 3 to 6 months used two or three inserts instead of the regular sized insert. I found that using these instead made the diaper less bulky and therefore leak less. They do retain a lot of stink, these microfibers. I followed directions perfectly, but found that only Rockin Green Hard Rock could knock out the odor of microfiber because of our hard water. That is why I didn't give them a perfect score - organic cotton soakers and hemp soakers just don't have the same stink issues.
