Get More Mileage From Your Baby's Onesies With A Onesie Extender

Updated on April 17, 2016

Are you amazed at how fast your baby outgrows their onesie?

The onesie extender is a handy invention that helps your growing baby get more wear out of his or her onesies. It's simply a piece of onesie fabric with snaps on both ends so that you can easily add extra length (up to 4") to a snap-crotch onesie or baby bodysuit garment.

We use these extenders in our house whenever we're behind in doing the laundry or haven't stocked up on the next size of onesies yet.  They're very practical and make a great little gift for new parents.

This is one of those products that made me want to smack my head and say, "Why didn't I think of that?!", when I first saw one.

Onesie Extenders are Tough to Find

For such a helpful baby product, onesie extensions can be hard to find in stores. I'm surprised that more retailers don't carry these. Even Amazon is frequently out of stock.

Listed below are places that I've found them online along with some other tough to find onesies products.

Tip: Read the item descriptions carefully to make sure the extenders will match your brand and size of onesies. Each manufacturer uses different spacing between the snaps.

So simple and practical. These extenders come in 5 different snap sizes to fit most brands of onesies.


Onesie Extenders on eBay

eBay is one of the best places to find onesie extenders. Read the product description carefully to make sure the extenders offered will match up with your brand of onesie. Some brands use a different distance between the snaps.

The Advantages of a Onesie Extender

These are the reasons my wife and I liked using onesie extenders so much with our babies.

  1. Save Money - Use your smaller size bodysuits longer and you won't need to buy as many onesies. Plus you'll get more use out of the ones you have.
  2. Easy to Use - Extenders don't take up much space, get washed with your regular laundry and attaching them is a snap. Literally.
  3. Flexibility - The onesie extender is great when you need a onesie now (not that any of us would get behind in doing the laundry). Just reuse a smaller size onesie with the extender.
  4. Your Child Can Wear Onesies Longer - Most manufacturers only make onesies in sizes up to around 2T. A onesie extension allows your toddler to wear theirs a little beyond that.

Long Sleeve Onesies - Good for winter

The long sleeve versions are great when the weather gets cold. They look cool under short sleeved t-shirts, too.

Sleeveless Onesies - Perfect for summer

We looked all over but had little luck trying to find the sleeveless onesies in stores. I don't know why more stores don't carry these. They're great to have in the summer time and look adorable.

Remember to use sunblock on baby's arms,though.

      What a genius idea, so simple yet so frugal and practical. I can't believe I didn't know these extenders even existed.

      what a great idea - i put my 2 month old son in a size 6-9 month onesie today and it is big around the neck but not long enough. I thought I wonder if they make some kind of an extender - I am so glad they do!!

      Onesie Extenders are a great idea. Babies grow so fast.

      Another hard to find item are the snap all the way down the front onsies. I prefer that type when diaper changes are messy.
