Help with figuring out what to charge.

[Countrymomma]

Hello there! First post, looking for some advice

I'm meeting with a family tomorrow who is looking for care. Both parents work the same 24hr rotation and would be looking for care 7-8 times/month. The little one is 2 yrs old and would be with me for 25hrs (6am-7am the next day) at a time. I would have a years schedule at a time, so i would know what I would be working a year in advance. This would include one Saturday and one Sunday a month, and occasional stats, depending on how the rotation fell.

I presently run mon-fri 7:30-5PM (40$/day) and have 2 other kids in care, plus my own 2.

Where would you even start to figure out what to charge? I'd like to figure out a set monthly amount.

Thanks in advance!
