For me, it is normal and there is no problem at all, because there are few opportunities to play outside and get in touch with outsiders, so there will be fear. Take the baby out to play more, get used to it, it's not a disease, don't think too much. When it comes to speaking, we should teach more and guide more. No, of course not. How can we learn without the opportunity to learn? Children are naturally fond of learning and can use various teaching tools to teach. They will be a very smart baby.
