Calling All Moms

I'm meeting with a lady tonight about watching her 4 month old daughter Monday-Friday for 2-3 weeks (or more) in December. If she asks me for a price point what do you think is a reasonable price?

I've been babysitting since I was 12 (18 now) but I've only taken the money the parents give me 😂 so I don't know what to charge... (I have the experience, I've taken child development classes & early childhood education class, I'm certified in CPR as well.)

Ps. My mom says $2.50 per hour (because she's only 4 moths) but it seems low?

Pps. I'd be traveling about 30 minutes each day
