I've been signing with Matilda since she was 7 months, and just using them when I say the word, so like for food I will ask is she finished & sign she now signs without us asking her, or if I ask she will sometimes sign "more please" and we will get her more food. Signing has really helped us communicate at this young age basic needs. We only use a few words so we have, "finished" "more please" "drink" "hungry"and a few other fun ones like "light" "dogs" and "bird"

Some of our signs are legit and some are made up (mostly the fun ones)
