It’s impossible to have Nick put his hands under a faucet and wash his hands, so a pan and a bottle with holes in the top are his sink and faucet. I use liquid castile soap because it’s easy to wash off and not toxic. He loves having his hands washed. As a rule, he likes to keep his arms close to his body, so let him know what you are doing and be prepared for some slight resistance at first. I stand just behind his elbow to keep him from spilling the pan. Once he feels the warm water flowing on his hand, he enjoys it. He will, however, pull his hands back close to his face several times. So be prepared.
