A single - handled faucet makes turning it on / off super easy with an elbow (
i.e. hands full of paint, caulk, sap, cement — you name it — and I just h.a.t.e. being sticky!)
Even after a child has been potty trained and has accepted the
full responsibilities associated with potty training
i.e. getting to the potty by themselves, pulling pant up and down, washing
hands etc, wiping seems to remain a parental responsibility!
