Bought again for a friend

I used these on my own bub to go over cloth nappies, just bought a set for a new mum planning to do cloth!

I brought my son a body suit with a 1 for his first birthday but he outgrew it before the day so I purchased the snap extenders and they were fabulous. They held the suit perfectly and I was saved money by not having to purchase another outfit.

Perfect bodysuit extenders so we can keep our tall baby in the current size of clothes while using larger cloth nappies!

Yes, we offer Click and Collect at our baby shop in Canberra, open 7 days a week.

Our extenders are color-coded for easy identification. The 9mm extenders have a white ring around them, while the 10mm extenders feature a silver ring.

We understand that getting the right fit is crucial, and we're here to help. If the extenders don't fit your baby's bodysuits, our return or exchange process is super simple. Just send it back to us in an envelope. As soon as we receive it, we'll either send you the correct size or issue a full refund, based on your preference. Your peace of mind is our top priority.
