This is the adorable moment a deaf baby communicates with his parents in sign language.

The footage, captured on May 1 in Maryland, shows seven-month-old Asher moving his arms to demand more food.

Asher's mother writes: ''Our son was born deaf, we know the importance of language input so we immediately started learning sign and using it with him.

''In the video he is at seven months old giving us a clear “more” sign to let us know he wants more food.

''He has 6 other signs he uses with us with in context.''
