* BigW, Target, Bonds and Best & Less also use 9mm snap button size on some of their collections. If you are unsure what size do you need, measure the size of snap buttons. We recommande to purchase both snap button sizes. SHOP HERE

We have tried our extenders on listed brands and we didn't come across any bodysuits that wouldn't fit one of our snap buttons, however, we can't 100% guarantee that they will fit all bodysuits as the brands might change their snap buttons from time to time. 

  1. Handmade in Australia
  2. Materials: jersey cotton, nickel-free snaps, polyester thread, calico
  3. Machine washable with like colors.
  4. Dimensions 11cm x 8cm

How to use:

Simply connect the fasteners of the Snap & Extend™ baby bodysuit extender to any suitable bodysuit and fasten as usual.  

Snaps are applied by an industrial machine, which is the most secure and durable way. We use the same snap suppliers as baby clothes manufacturers, ensuring a perfect snap. 

One extender can be used on all sizes of bodysuits. Made to best fit size 0, the extender may crease a little on smaller sizes due to a smaller spacing of the snaps (this does not take anything from its usefulness).

    Great quality

    Great product - simple but effective and well made, sturdy construction with the reinforcement under the studs. Works exactly as I wanted it to for my cloth nappy bub. Love it.

    Perfect! Just what we needed

    I love these extenders! My daughter has a long torso but she really skinny so she grows out of her bodysuits length wise before the rest of her body is ready to move up a size They're made really well, 100% recommend

    Big cloth bums

    We love these extenders especially for big cloth bums :) my son is very small and going up a size to fit his cloth nappy means his suits swim in him. These extenders allow us to stay in a smaller size suit until he needs to change size :)

    So handy!

    These have been great, we’re using cloth nappies and it was hard to get a good fit with bodysuits on our long skinny bub with his big cloth bum! This lets us use the right size for his body while giving the extra length we need.

    Great for long babies and cloth nappies!

    I love these extenders! I have a loooooong bodied baby and she was growing out of all her bodysuits lengthways with so much room left sideways to grow into. Coupled with using cloth nappies I wasn’t really able to use most of her bodysuits until I got the extenders. Absolute lifesaver!

    Great way to get more life out of bodysuits

    Nice and stretchy- especially over cloth nappies and a great way to extend the life of body suits.
