Hi.. My daughter is 4 years old. She has started offline school for the first time. She doesn't cry or say anything while going to school but when she reaches school, she is sleepy and tired. She constantly complains that she wants to sleep. After school, she takes afternoon nap after that she says she wants to sleep again. At night when I put her on bed , she doesn't sleep easily. I feel that she wants to sleep but feel uncomfortable. What should I do?
