We use try when we want our baby to develop self-sufficiency. At the playground, we could sign try when our baby insists in receiving help for a task we feel he or she can complete on their own.
Try is better taught from real-world interactions, rather than from a flash card. Try is a sign that we use when our babies are exploring and discovering their independence. Both in spoken form and signed, try encourages exploration.
