How do parents write sick leave notes for students?

1, dear teacher: My child xxx can't come to school because he needs to be nursed at home or must be hospitalized because of X disease. I will take X days off on my behalf. I hope you can approve it. Thank you. Here, I salute.

Dear teacher, my child xxx needs to take X days off due to illness. During his absence, parents will be responsible for long-term care, parents' signature, contact telephone number, date, study, life, health and the safety of the classmate. If there are any consequences, you are responsible for it yourself. Please approve. Thank you. Sincerely, salute.
