(CNN) – It can be frustrating when you know your baby wants something, but you just don’t know what it is. They can’t just tell you, but with a little work, they can sign it.

Parents know this conversation too well. Your baby is clearly trying g to tell you something, but they haven’t mastered the use of words yet. That’s why some parents have turned to sign language as a way to communicate.

“There are a lot of benefits to learning baby sign language; typically babies who sign typically tend to have better vocabularies when they do start speaking and they tend to speak earlier than those that don’t. It also reduces the frustration that parents feel when they can’t understand their baby, and their baby can’t understand them. So it’s a great way to communicate with your baby and reduce temper tantrums.”

There are websites, DVDs, and even classes parents can take to learn the basics.

“Studies have shown that children who have signed with their parents as babies have higher IQ’s than those that don’t. The average is about 12 points higher, in addition children who sign with their parents as babies score higher on verbal tests when their older when their in school.”Copyright 2015 CNN
