As babies progressed in their learning, they often begin to combine signs with vocal words. If you will start your baby to sign more early, even when he is a toddler, your baby will learn to combine the sign. Most of the babies learn to combine the sign almost at 12 months but some babies learn to sign at the age of 24 months. Many babies are able to combine at least two words at the age of 24 months.
It is truly impressive for your baby to combine more than one word. Combining signs help your children to develop more fluent and effective communication skills and babies will learn to speak much earlier of their age. As your baby grows, he will be able to combine more than one word. As your baby’s learning abilities speed up, he will begin to combine three, four or even five words and these combination will really help you a lot to eliminate the guess work. For example, if you baby has two teddy bears, he will be able to tell you that he wants his red teddy bear.

Some common combination are as follows.
•Object + Color
•More+ another sign
•Another sign + object
•Go+ person or any object
