Babies grow. Much too fast. Before you know it, the new onesie is already a size too small. With our onesie extenders the bodysuits can be worn for a while longer. That's sustainable and also good for your wallet.

The set "Merinomo" contains 2 onesie extensions with 2 different button sizes:

  • small: 7 mm
  • large: 10 mm

Since the manufacturers of onesies use different button sizes, you can be sure with this set that at least one of the extensions will fit your onesies.

Material properties

  • high-quality organic cotton and merino wool, robust and durable
  • the small metal button is silver and the large metal button is red for better differentiation of the sizes

Application possibilities

  • as an extender, if the onesie still fits around the top, but does not close at the bottom
  • helps with nighttime diapers, so that the onesie does not fit too tight

Our onesie extenders fit on most popular body brands. These include BabyClub (C&A), earlydays, George, H&M, Kanz, Liegelind, Lupilu (Lidl), Next, organic (Hessnatur), Petit Bateau, Steiff, Topomini (Ernsting's Family) and many more.

  • Please do not use bleach or fabric softener.

Please note that some brands use smaller and larger snap fasteners and yet are not compatible with our body extensions. In addition, the manufacturers change the snap fasteners of the bodysuits from time to time, so we cannot promise that our information about suitable manufacturers is always up to date. Some manufacturers also use only two buttons or very narrow button spacing.

Please check the diameter and button spacing of the press studs on your bodysuits before you buy to make sure that our body extensions fit.
