What's the best way to respond in this situation?
My daughter is 2yo and she gets so anxious talking to other adults in playgroup she puts on a baby voice and uses one-word answers, or she makes these strange little noises instead of using words. She sounds really stressed compared to how she is when she's just talking to me, likely she's forcing the words out, but she wants to continue the conversation so I just let her.
What can I do to make it easier?
Other times, when people try to talk to her she stays quiet then she'll say to me, "can we play with something else?" because she wants to get away. All the adults are so lovely and friendly and patient and experienced dealing with little kids.
