My baby takes everything else but just doesnt take the teether , im worried as other stuff might cause infection..how can i help my baby to use the teether?

I've babysat for some families here and they used frozen bagels or frozen waffles as teethers. The spongey texture of these frozen baked goods absorbs drool and they taste yummier than a teether. However this option is for older babies and must always be supervised cos baby can choke from these treats. I've also seen families using home made popsicles (made out of juice or frozen fruits like apples) but again, for older babies and absolutely important to have supervision to prevent accidents.
