You’re welcome is signed the same way as Thank you. Take your flat, open, dominant hand, and starting from your chin, take your hand out as it arcs down and away from your face. It is as if you are acknowledging that your baby has thanked you, so you are mirroring the polite gesture back, like thanking them for thanking you!
Teach your toddler the you’re welcome sign so that they learn polite responses in situations where people want to show gratitude for kind gestures.
This is a wonderful sign to introduce early in their life, as we begin to teach our babies the meaning of gratitude and good manners. Because this is an abstract concept, it is best learned through imitation.
