We have used Flips since my baby's umbilical cord fell off, when he was about 3 weeks and 8-9 pounds. He will turn one year in two days, and we just moved up to the largest rise setting (he is 22 pounds now). I fully expect to use these until he potty trains. They have fit great and held up well with repeated washings. In fact, at 8 months, we ordered 2 more covers for day care and compared them to the ones we had been using- you could barely tell which were new and which we used! Maybe a very slight stretching at the gussets, if you really were looking- but they still work just fine. Initially, we doubled the stay dry inserts at night. Around 4 months of age, my baby began wetting so much that he leaked at night. Now we double with a hemp insert and have had no leaks due to saturation. We have had some leaks due to fit as he has grown, but the issue was resolved by adjusting the rise or tightness at the waist. We exclusively cloth diaper and have 10 covers (had only 8 covers until baby was 8 months old and that would have been sufficient but I wanted more so my day care provider would have a clean cover for every change), 30 stay dry inserts (which is more than plenty- probably could've bought 24), and 4 hemp inserts in our stash. I've had no issues with the inserts bunching or moving around- just lay them in there and you're set. Do be sure that no part of the insert pokes out the leg hole (see my photo of month one- that probably ended in a leak!). Also make sure to always have the microfiber side down as my mother-in-law once put it in upside down and my son developed a rash quickly. We tend to wash every other day but can go every three days if needed. Initially, we had to wash every other day and sometimes every day because we ran out of covers when my baby was younger used to poop more frequently. When they are really little, the cover pretty much always needs washed if baby poops (until my baby started solids, when I could spray or shake the poop off). Sometimes it needs washed because the stretchy tabs are saturated with urine after an overnight usage. With all that washing (I do a prewash with half detergent, wash with Charlie's Soap on hot, and extra rinse in my front loader), the diapers and inserts look like the day I bought them. I do always line dry the covers (they dry super fast) and use a half cup of bleach on the inserts about once a month to get rid of stains and funk. I will also add that we used the disposable inserts on a weekend out of town. They were great! A little pricier than non-premium disposables (when we used sposies with our first two kids, we purchased them from Costco at around twenty four cents each). I changed diapers every 2 hours in the flip disposable insert, too, which was somewhat more frequent than a regular disposable. I haven't tried just a disposable insert alone at night- I don't think it would hold up without leaking. When traveling, we brought the hemp inserts and used them under the stay dry insert overnight. I have used the disposable inserts underneath a stay dry insert overnight when my hemp inserts weren't dry enough to use (they take forever to dry once washed), and that worked great. I have found cloth diapering to be much easier than expected. I EBF the first 6 months, so I just tossed all diapers in a dry pail without prerinsing. They always came out clean from the wash. When we started solid foods at 6 months, I used the shower head to spray the poopy diapers off into the toilet, wring out, and drop in the pail. By 8 months, my baby was at a point where I just shake the poop off in the toilet, no spraying needed. We tried those flushable liners, but they gave my baby a terrible rash. Cloth diapering has been an adventure, requiring a little problem solving as baby has grown and changed, but has definitely been economical and resulted in much less waste. I calculated that we broke even on our investment after using the diapers, inserts, wipes, 2 diaper pail liners, and wet/dry bag for the diaper bag for four months. Now it's like we diaper for free, aside from a little extra on the water bill. I haven't tried any other cloth diaper because the flips were a great price and have worked well for our situation. I hope that my review helps you decide if they will be a good fit for you!


I love the Flip diapering system! They fit very well, hold in leaks very well, and are very durable. I get more than just one diaper change out of it unlike the pocket diaper. The only things that may be a negative are that they aren't the easiest diaper to diaper-on-the-go. Trying to do a Flip diaper away from home gets my hands messy. And also when my baby was a newborn it didn't contain the breastmilk poop very well. But now at age 2, it is one of my favorite diapers to use on her!


love these covers. I have 2 kids in cloth and 4 covers per kid. The only "bad" thing I have to say about them is I wish they had gussets. I don't use them over night because I get leaks around the legs. I wish so much they would add gussets. I was also unable to use them on my new borns because of leg gap. a good thing is they are the only diaper that fit my now almost 3 yr old. other diapers stoped fitting her at almost 2


I've ordered eight Flip covers now, all in different colors. Choosing colors can be a challenge when 1) you only want neutral colors (two boys) and 2) the colors on the screen (on several different devices) don't seem to be super accurate. Having now made the "risky" color purchases a couple times (sometimes with success, other times I had to trade them out with a friend's stash) here are a few of the "real" colors: "Noodle" is actually a really smooth cream color, perhaps leaning a tiny bit yellow but mostly a true cream. It's a nice neutral but still attractive cover. "Bubble" is a pale, pale lavender (despite looking a bit blueish online - definitely purple in person). Not neutral. I traded this into a friend's "girl" stash, for "Twilight" (a hint darker than pastel blue). "Grasshopper" is one step away from day-glo neon green. It's a little too muted to be true day-glo, but it's really a light neon green. I wouldn't choose it again for the boys, but it's not exactly a girl color either. Just...neon. That said, it's neutral enough to use. "Sassy" is construction site red-orange. You will not lose sight of your baby's rear when this cover is on it! Seemed way too sharp a color at first, but ended up being really cute with shirts - most often it looks bright red in photos. Good luck choosing!


At first I loved these diapers, they were great for the first 4 months. But then when my baby started crawling and especially when she started walking, the inserts would move around and leak ALL- THE- TIME. I'm disappointed because I invested a lot of money in this style and now will be needing to buy additional diapers.
