For the past year I have been watching my niece and nephew from 730-430 daily. For this my sister pays me $75 per child per week ($15/day). The children are age 2 (still in diapers) and age 3. I feel like I'm giving her a great deal, but she is treating me like I'm ripping her off. I thought full-day day care ran more in the $25-30/ per day range. Am I off my rocker for feeling like she either needs to treat me better or pay me more?
