Badly designed for a baby's mouth. Avoid,
Amazon Verified Purchase(What is this?)
This review is from: First Years Floating Stars Teether (Baby Product)
Initially, this item seemed ideal. It gets nice and cool in the fridge and is ok for the freezer if needed. However it has one major flaw. The seam around it is entirely useless for putting into a baby's mouth.
On the actual spheres, it is not bad - and probably passable, but the more the baby needs the teether, the more of the sphere ends up in their mouth. It is when the part that connects the spheres comes into play, and that has thin edged sharp plastic which is dangerous for a young baby's teething gums.
I cannot underline this enough - Do not buy this item.
