My onesie extender bunches, is this normal?

Yes!  The onesie bummsie extenders have been designed to bunch.  This is due to the spacing of the domes on the bodysuits.

How do I know what size extender I will need?

This all depends on much extra length you need and is different for everyone.

If the onesie is starting to get difficult to do up, then a short extender will be the right size for you.

If you need more length to get over the nappy, then a medium extender is the one to use.

We sell our extenders in individual packs or in 3 packs with 3 of each size to make this really easy for you.

How will I know when I need to use a onesie extender?

The problem most mums face is the onesies become too short while still fitting through the body.  Moving to the next size isn’t always practical especially when the onesie is so big and baggy.  If you are struggling to snap the domes in the crotch then it’s time to grab a onesie extender!
