My daughter aged 3 years and 8 months old. She feels very shy and scared while talking with strangers. Last one week we visited grandparents place. She was very happy and enjoyed there. Before,She used to talk very few words. But for the past 2 days she has improved. I could see changes in her. I'm afraid that speech regression may come again as only myself and daughter are there in home. How to make her speak well? She talks better only if she's happy. Pls give some tips.
