My DD is nearly 4.
She has been going to nursery since 1.5 years old and bonds well with the staff and children. She's also generally a very chatty girl at home, and nursery staff say she is funny and generally very happy.
However, I noticed that when unfamiliar adults speak to her, she goes completely blank in the face and does not respond. She cannot even say "thank you" when prompted. It's as if she's frozen. However, once she spends at least half an hr or so with an adult, she then warms up to them and is able to interact. In fact, she loves to interact with people.
I'm worried that her blankness and lack of response will seem rude to people. I fee a bit embarrassed by it as literally anything said to her by an adult is met with silence. She's due to visit her new school in a few weeks for a session and I think she'll probably end up not saying a thing even when asked.
Is this unusual for her age? Is there anything I can do to encourage her to talk? I have tried but to no avail. When I ask her, she comes up with an excuse like "I was just about to cough" or the like 😂. It seems she understands what she's expected to do but just wouldn't do it. I think eventually she will gain confidence and COVID and lockdown probably have a part to play in this. But what can I do in the meanwhile to help her? Any advice would be appreciated!
