We have been signing with Jackson since he was born and we're finally starting to see some progress. He knows and understands the signs "more," "all done," "doggie," and "kitty." We've also started introducing "milk," "eat," "drink," and "thank you." I think signing is so helpful for easing a baby's frustration before they can speak! Want to learn more about signing with your baby? Check out this awesome article Misty Weaver with Baby Sign Language put together for us!
To sign Mommy extend and spread apart your fingers. With your pinkie facing forward, tap your thumb on your chin.
To sign Daddy, extend and spread out your five fingers on your strong hand. Tap your hand on your forehead. Done right you will look like a turkey.
The sign for Milk is a lot like milking a cow, but without the vertical motion – you are just squeezing the udder. Take both hands, make them into a fist, relax, and repeat. You will notice most babies have trouble moving their fingers together this way, but any kind of repeated squeezing and relaxing of the hand is likely Milk.
To do the sign for More, flatten out your hands then bring your thumbs under to make an O shape. Then, bring your hands together and separate them repeatedly. Baby will often simplify More by clapping their fists together. As they get older and more proficient you may want to encourage the more correct sign of flattening out their hands and creating the O shape with their thumbs as a fun way to help them develop fine motor skills.
