Close to signing More

Last night Shawn had porridge with cod fish and green peas. I served him white grain porridge first while the fish/peas were still steaming away. So we started with just the porridge with flaxseed topping.
Then when the fish was ready, I told him, "Now it's fish time". It took awhile for him to react.
Then I repeated, "Mommie is giving you fish. Do you want fish?"
Shawn signed and said "More, more... ish, ish" (right hand tapped left wrist). I reckon it's quite close to More sign fingers to fingers.

And it went on and on until the bowl became quite clean, left some fish bones and bits of green peas.
