Social skills games for shy children
We tried to work on this at home first. Most of our children are not so shy they won't talk to people upon warming up to them after a few minutes to a half hour. We also try to take our children to our business trade shows/market s so they are helping and working with people one on one. They do tend to outgrow their shyness given the chance.
Our 15 year old use to hide under the table when she was younger and now she is the spokesperson/sales person of her own soap business. She has taught two soap making demonstrations on the farm as well. We didn't push her or force her but gave her opportunities to grow and I think those opportunities helped her outgrow her shyness.
