Question about part time care

[mom.to.one]

I was at a play group that I attend last week and was chatting with another Mom and she has asked me if I will watch her daughter part time. Right now she has a nanny watching her daughter but doesn't think the nanny is changing her diapers often enough. The Mom is driving to another town 1.5 hour drive away each way for work and back. Her daughter just turned one and is a few days older than my son.

Is $11.00 an hour a good rate for part time care? The rate here for daycare seems to be about $50.00 a day for full time care.

Who covers the food?

She cloth diapers, do I send her home at the end of the day with a bag of dirty diapers?

She asked what kind of days I would like to work (weekdays or weekends) I said I could do whatever but I am now thinking that it would have been better to do a Tuesday Thursday or something that way I could take other kids during the week.

I would like to sign a contract to protect myself. Any other things that I should know about or advice you have?

Thanks!
