Happy Heiny’s OS and Organic OS Review

Happy Heiny's OS (improved)
Happy Heiny's OS (improved)

I will readily admit to putting the old version of the Happy Heiny’s OS diaper at the bottom of my list of favorite diapers (I also have a video review of the older version).  I had a lot of leaks with the one I had for my first son when he was younger.  I believe I traded it off a LONG time ago after getting frustrated.  When I wanted to review newborn diapers I wasn’t sure I would even attempt the Mini OS from HH but I knew I owed my reader’s this so I did.  Along with 2 Mini’s HH also sent a few of their other products.  I was secretly thinking….. “oh great… another leaking OS” but Linda assured me this was an improved version.  It totally is!!!  I have had a very good experience with the new version, so for anyone who hated the old ones, don’t rule out Happy Heiny’s until you try the latest version.

Ease of Use ✩✩✩ Velcro diapers are very easy to put on a baby during diaper changes.  One thing I noticed is that often I had to undo and redo the velcro because the thicker strip doesn’t lay as close to the baby as some others and it wouldn’t be as tight the first time around.  Sizing is easy, 4 rise settings that snap up or down.  The most annoying part of this diaper, the velcro tabs, make taking the diaper off and putting it in the pail/ wet bag harder.  You don’t attach the velcro to the laundry tabs, instead, you wrap them behind the diaper and attach to one another.  This is definitely more time consuming than tabs.  Stuffing a HH is very easy thanks to the generously wide pocket opening, good enough for a Dad or Mom. *note I have not tried the snap version so it might be one star better…

Bang for the Buck ✩✩✩✩ A HH OS is 18.95 and their Organic version is 20.95 (with no insert).  Their regular OS is in the same range as other OS diapers, maybe 1.00 more than some.  The Organic is fairly unique since most pockets are lined with microfleece or suedecloth so you will have to pay extra for that.  By the time you add the insert the cost is rather high but if you want organic fibers next to baby’s skin and the convenience of a pocket you might be willing to pay.

Performance ✩✩✩✩ This is where the new OS really shines.  I had no leaks on my toddler, and very few leaks on my newborn, even when he was at his smallest.  We began using the OS on him (both organic and non) after his stump came off.  Because the waist is so long to accommodate toddlers you have to be careful when putting it on to make sure it is as tight as possible, if not you might get a leak.  If you pair the Organic OS with a hemp Stuffin’ you have a great night time combo.  We used the regular OS with a newborn bumGenius! insert so it was trimmer than I expected.

Fit ✩✩✩✩✩ I was very skeptical that it would fit my newborn well since it looked so bulky, but once on it wasn’t bad.  Using smaller inserts helped lessen the bulk.  It says it starts fitting at 8 and my son was probably 9.5 when we tried it on him and it fit.  The tabs were all the way crossed over on his waist.  He is now 15 pounds and has 1 set of snaps exposed on the rise (the “small” setting).  My toddler has 2 sets of snaps exposed and he is 26.5 pounds and 34 3/4 inches tall.  He still has PLENTY of room in the waist (the tabs actually still cross a little) and another rise snap to go.  This is one versatile diaper!  (you can see how it compares to other OS diapers on a newborn on my OS Chart.)

Overall- Color me surprised at how much I like this diaper.  It has function, fit, performs great, and has a very diverse range of colors and prints, more so than pretty much any other pocket diaper out there.  The tabs do cause diaper chains even when I cross the tabs the way HH says on their website.  This does frustrate me because if it weren’t for that I would use these way more often.  I wish I could say how the snap version works and if it fits as well as the velcro.  When I first saw a HH OS I was turned off by the appearance of the wide velcro strap, but it doesn’t bother me so much now.

Where to buy: Kelly’s Closet (affiliate link) has the Organic OS, Regular OS, Mini OS, and Snap OS in all of their pretty colors and prints.

Happy Heiny’s sent their Organic OS and Regular OS along with other products for the purposes of this review.  No other compensation was received.  All opinions are 100% my own and genuine.

  • I am so glad to see this review! I am someone who has tried the older versions of HH (they were among my first cloth diapers to try)… and they were okay but after trying other brands, they have definitely become my least favorite. They are probably the least used but falling apart more than the others.

    I am so glad to hear they are improved… I must try one now!

    • The new fit is improved. I have only used them for 3 months so I have yet to see how they will hold up for a long time. The tabs have caught many things in my dryer though 🙁 The only downside so far

    The Happy Heiny One Size is my go to overnight diaper, I just LOVE it! My son is a super heavy wetter and this is one of the only diapers that will not leak on him for overnight use (the Kawaii Overnight diaper being the other one). I am so glad you did this review! I use the snaps right now for my 8 month old son and they work great. I’m glad to hear they fit a newborn so well as well. We didn’t cloth diaper my son when he was born and ended up switching to cloth when he was 5 months old, so I have a huge stash of larger size diapers as well as one size diapers, but no newborn diapers. When we have our next baby I will definitely need to try these once the cord stump falls off!
