To do the baby sign for trade, make a modified X or F hand shape on each hand. Hold one hand forward and one hand near your body. Then switch the positions of your hands, to signify that you want to exchange something with the person in front of you.
We mainly use trade when teaching our babies how to exchange things politely.
Use the trade flash card in conjunction with flash cards for a variety of toys or clothing items, for instance, "I will trade you my hat for your shoes." Negotiation skills are a great way to equip your toddler for their transition into play group or preschool.
