The other issue was PVC in a lot of the bath toys which children then put in their mouths. Safe Mama has a few alternatives to suggest, including the line from Boon Toys which we've highlighted in the past here.
As far as keeping the toys clean, she suggests:
• Air-drying them and storing them away from the toilet
• Washing them with soap and water or in the dishwasher
• Simply avoiding toys with the holes in them
This all sounds pretty common sense to us. We have a few of the Boon toys and a few pvc-free squirties and we always wash them off after each bath and then air-dry them. Our daughter's favorite toys for the bath are just simple stacking cups with holes in the bottom. Disinfecting the tub often is also a part of our regimen.
Still, these are good tips and important to be aware of. Find the complete article and the link to a video from the Today Show here.
