Set of 3 NEW onesie/one piece extenders, Add a size to your bodysuits.
These are a must-have! I have personally saved so much money using these. You can typically get another 2- 3 months of wear out of your favorite onesies by attaching these. These are also perfect for making up for that little bit of extra bulk from cloth diapers!

Over 1,000 Sold.
I have 100% positive feedback, and called "One of the best sellers on Etsy" Here's more of what Customers are saying...

*These are AMAZING and work perfectly on every onesie I own. I have recommended these to all my mommy friends. Thanks again

*Great product! A must-have for cloth diapering mamas! I haven't come across a brand these won't work on! Thanks!

*Absolutely perfect! very well made, snaps on easily to add just the right amount of length. would recommend to anyone. thank you for mailing so quickly!

*we're very happy that we get to use some of our favorite onesies a little longer on our lanky little boy! thank you so much! very happy with the purchase.


1) I use Nickel free snaps! (nickel can cause rash or skin irritation and is a known carcinogen). My fabric is also free of AZO dyes.

2) Three different snap sizes (small, medium and large). The size refers to the snaps. The medium sized extender will probably be the one you will use most. Between the 3 sizes there should always be an extender that fits! These will work on onesies from 0 months all the way through 24 months. I get lots of emails asking if they work on Carter's, Gymboree, Baby gap, etc etc. The answer is "Yes!" To my knowledge there are only 2 brands they do NOT work on: Hurley, and Calvin Klein (since they have a custom snap used only for their brand which is not sold)

3) Cute patterns! The cute patterns aren’t just for show though, they make it easy to grab the right extender because each size will have a different pattern. Plain white is also available.

4) Quality. I use only 100% cotton flannel. I pre-wash in free and clear detergent and dry (pre-shrink) all of my fabric. This does take extra time and effort, but it’s worth it because the extenders don’t end up shrinking and getting funny shaped. I also don’t use cheap snaps, I use very high quality USA snaps. This ensures that they fit the standard sizes used in your onesies, and do not break or come off in the wash. You will be using these extenders a lot, so I make them to last!

5) Buy more than 1 set and get FREE shipping on all additional sets.
This helps save money if you are wanting multiple sets. They also make great baby gifts.

All items come from a clean, smoke free, and pet free environment. And are handmade here in the USA by my mom and I.

Thanks for looking.

Frequently asked questions about honeybunnyandbear

Snap size varies depending on brand. We always recommend customers get the variety pack to have 1 of each size on hand initially. Once you begin using them, if you decide you would like extra of a specific size that you use more than the others, you now know what size you need and you can place a custom order. If you only use 1 brand of bodysuits and don't plan on getting any more in the future, send us a message and we can help you just get the size you need.
Yes. Simply go to our ad titled "2nd Order Options" and the drop down box will let you choose exactly what you need. You can also just add any one of our bodysuit extenders listings to your cart and leave a note at checkout specifying the snap sizes you want. We normally leave a couple sets of each style unsnapped for this purpose. If the style you selected is not available for a custom order I will message you and let you know so you can choose a different style. Please only place a custom order if you are sure you understand snap sizing and which sizes you need.
Longer extenders tend add too much length and make the top of the leg hole of your babies bodysuit higher, which means that it could peak out of the waistband of the pants. The length we make our bodysuit extenders adds plenty of length without causing this problem. The longer length is very unlikely to be an issue for babies in bigger bodysuits (18 months and up), and we have made several longer sets for older toddlers with feeding tubes so that they can keep their site clean and safe.
Shorter extenders would make sense for preemie or newborn bodysuits (although normally the standard length is just fine for newborns)
We are happy to make whatever you need!
The bodysuit extenders are meant to be covered with pants or shorts. Other than being cute, the patterns serve as I way for you to quickly and easily be able to look at an extender and know which one it is without having to check and compare the snaps.
To my knowledge there are only 4 brands they do NOT work on: Hurley, Nike, Blanks Boutique and some of the Calvin Klein bodysuits (since they have a custom snap used only for their brand). These will not attach to plastic snaps.
If you encounter a 2-snapped bodysuit, simply leave the middle snap on your extender unsnapped. If you would rather custom order a special extender for your 2-snapped bodysuits just let us know.
The reason we use flannel is because it is soft and durable and the snaps attach very tightly to it. Remember, there is going to be a diaper between your baby and the extender so it should not be an issue.
Yes! They are made in a smoke free and pet free home. I also use scentless eco-friendly free and clear detergent to prewash the fabric.

ONESIE EXTENDERS. Add a size to your bodysuits. Also great for cloth diaper wearers.
