Business is signed just a bit like busy, so be careful not to get the two confused. To sign business, take your non-dominant hand and, drawing it into a fist, lay it horizontally in front of your body. Then take your dominant hand, form the ASL letter B sign with your palm facing forward, and move it side to side a couple of times.
While busy is signed with the non-dominant hand open and flat, facing down, the business sign has the non-dominant hand drawn into a fist.
Teach your toddler the business sign when they start showing curiosity for the kind of business that you or your spouse do, especially if you do a lot of work from your home. If your business deals with tangible objects or products, it may be a great opportunity to learn the signs for those things and teach them to your baby, too. Children are naturally curious, and they want to know what Daddy and Mommy are up to sometimes!
This is a useful flash card taught best in conjunction with your actual work, or when your toddler shows curiosity about the business or work that others do in their immediate environment.
