Greatful day, first thank you to my future employer for this opportunity. I'm a sincere person, and I give my best to my profession. I hope you can hear my heart's desire to get a job sooner or later. Thank you!
Anyway, there's no experience taking care of children for others, but I have plenty of experience with my own. introduce myself as a parent: Self-discipline is a key; god-fearing is a must; passion is required; it is the meal of our soul; make it strong whenever it happens for your entire life, safety, security, and protection; 
Absolutely, tenderness, love, and care are my passions as parents. If I take care of kids, I will be taking care of them too, treating them as my own child. highly appreciated and respect you as my future employer.
