As my son always kicking the quilt during the night, so that he's easily got flu or cold for the next day.
Would you pls let me know how to prevent him from kicking the quilt during the night, so that I could have a good sleep during the night (as I need to help him covering the quilt again 4 or 5 times during the night, so that I didn't have enough sleep/deep sleep during the whole night).
