The ever-resourceful Heather has a great bath toy hack:
New bath toys make bath time more fun for everyone, but how do you get them without spending a dime? Look around your house and you’ll be surprised by all the great "new" bath toys you’ll find.
Ideal bath toys dry easily and are safe for your children to play with. The kitchen is a great place to start looking for colanders, measuring spoons and cups, turkey baster, and plastic dishes. Do you have small pool toys in your garage or outside? Bring them in for something new to play with in the tub. The same toy in a new play setting will often yield unexpected delight and new imaginative play. Have any baby toys your kids have outgrown (teethers, balls, and other plastic toys)?
Be sure to store those new bath toys in a breathable container so that they will dry thoroughly. Look for a breathable container you already have like a plastic colander, plastic mesh bag, or a clothes hanger with clips.
Now you may have more bath toys then you know what to do with, so consider rotating them to keep bath time more interesting for you and your kids.
