The Little Mermaid’s Ariel is a brave girl who overcomes so much for her dream. Luckily, your child doesn’t have to fight sea monsters in order to stop thumb sucking! Just slip on a Mermaid Thumbsie® Thumb Guard and they’ll be well on their way to breaking their thumb sucking habit. Take the time to find out how to measure your child’s thumb accurately for the best fit. There’s nothing fishy here!

What size do I need?
Fits Like a Glove

The thumb guard is worn like a glove, it fits over the thumb and is secured with Velcro around the wrist, so is easily adjustable. The glove will fit either thumb and will not limit the child’s ability to play or use their hands.


Outside: Multi-coloured mermaids on a dark blue background 100% cotton fabric, Oeko-tex certified.

Inside: Thumbsie® branded cotton fine warp satin fabric, Oeko-Tex certified.

We suggest washing by hand or in the washing machine at a low temperature.

Approved by professionals

We are delighted that Thumbsie® has been ‘Approved’ through the Oral Health Foundation Accreditation Scheme since May 2020 and that they recognise Thumbsie® as a thumb sucking aid.


Thumbsies® thumb gloves are available in extra small, small, medium, large and extra large. Please use our size guide to get the best fit.
