Babies will chew anything - toys, pebbles, fingers and visitors fingers, most of which really shouldn't be put anywhere near their mouths.
This is natural - especially when teething.
Teething is an amazing process The gums are gradually breaking down to allow the teeth to come through.
This can be very painful... so your baby chews, both to help the gums break down and to soothe the resulting ache.
Hevea Teethers are made from 100% natural rubber which means they are soft and pliable but firm enough to give the soothing pressure on your baby's gums that they're craving.
There are plenty of plastic teething rings on the market but scientists are asking a lot of questions about Bisphenol A and phthalates, two chemicals found in the plastic used to make many of the plastic toys babies put in their mouths.
The answers aren't conclusive, although the evidence was strong enough for both the European Union and the US Environmental Protection Agency have banned six key phthalates.
Bisphenol A, also known as BPA is harder to ban because it's hard to remove from the plastic making process. Plastic teething rings, bath toys and pacifiers spend a lot of time in your baby's mouth. If you heat them to sterilise them, you're increasing the chance that BPA is released.
