Bonjour,quelqu’un pourrait t’il m’aider à rédiger un cover letter ou je doit dire que j’aimerais postuler en tant que nourrisseur de poisson Merci

Hello
I am writing to apply for the babysitting. I am a sixteen year old high school student.
I am really interested in this job because i love kids and spending time with them.
I have never worked with children before but i have 3 siblings that i love taking care of.
I can play with them. help them to do their homework and cook for them.
This is why I think that I would correspond to what you looking for.
Please don’t hesitate to contact me if you need any information.
Thank you for your time and attention
Best regards
[ et tu signesssss]
