Frown is a natural sign. From a smiling or neutral face, make a frowning face and repeat the word frown until your baby associates the sound and name to the facial expression.
Teach your toddler the frown sign when you are acknowledging that you see they are sad or upset about something. So it is important to teach this sign along with other emotion signs and possible reasons that cause their sadness or being upset.
Teach your toddler this sign along with the other signs that signal negative and positive emotions - as well as the situations or occasions that trigger such feelings. Having a sign for those feelings and triggers can actually help your child become less frustrated as they can now communicate to you the cause of their upset.
