How to Sign the word Drink
Drink! Babies love this sign because it's easy. Within drink, we can later find out what kind of drink your baby wants. For now we will focus on the sign.
This sign basically looks like you are drinking something. You simply take your dominant hand (in most cases, right), place it near your face as if you are taking a drink, and that's it!
I have provided photos and slides showing both front and side versions for clarity.
