In June, my child was covered with a quilt.

That depends on whether you are a thin quilt or not. Or a thick quilt? How much is the quilt? It's normal if it's a thin quilt under two pounds. Children's ability to adjust temperature is poor, and the temperature difference between day and night is also large. It is a self-protection phenomenon that children need quilts. As long as the child's temperature is normal, there is no night sweats, his diet is normal, and he is full of energy during the day, there is no need to worry.
