When my daughter was a baby and not speaking, my wife and I taught her to use sign language for several words, including “More.”
“More” is supposed to be signed by tapping the fingertips of both hands together several times. My daughter learned this sign and several others until she was able to speak. It was helpful and damn cute.
We tried to teach our son this sign, but he rejected it, developing his own, equally effective sign.
I kind of love the idea that he refused to conform to standard sign language and created his own sign.
To be honest, I like his version of “More” better.
