To sign kid, close your dominant hand into a fist, with only the index and pinkie fingers sticking out. Then hold the index side of your hand up to your nose, while pivoting the rest of your hand at the wrist a couple of times. It is as if you are referencing stinky children when you make this sign!
Teach your toddler the kid sign along when referring to them, their siblings, cousins, friends, and classmates. Teach them also the child/children sign so that they understand these two words are synonymous.
This is a useful flash card taught best in conjunction with all the other signs that designate your baby or toddler and their siblings, cousins, friends, and classmates.
