Check out the Aqueduck. It's sold online at Amazon: Aqueduck Bathroom Faucet Extender - Aqua
Retail value is around $20.
Here's my honest review. Pros? Don't break your back trying to pick your kiddo up to clean their hands.
Cons? It's only for the bathroom sink. We do most of hand washing in the kitchen.
Pros? Adorable & catchy name and logo.
