Thank you for this great review. Firstly, I would recommend using the gummee glove without the heart teething ring attached. This will allow your baby to use the gummee glove more easily, as it will be lighter. Then introduce the heart ring into the glove when they have more strength and dexterity. You can also put the gummee glove into the UV steriliser. It is a tight fit, but it will go in, all you have to do is turn the glove over after the first cycle and then run again. Hope this helps. Thanks, Steve Boothby, Gummee Daddee.
