I recently came upon these Re-Play children's dishes at our local Walmart. They're inexpensive (approximately 5 a package), made from recycled milk jugs, BPA free, & manufactured in the USA. The plates have deep wells, so it's easy for E to scoop her food , & the plastic very thick & sturdy.
While the plates are not microwavable, they're dishwasher safe & durable as all get out. If you're in the market for some sturdy, environmentally friendly children's dishes, I'd highly recommend buying from Re-Play. They're fabulous!
