I did "day care" as in I watched my niece. I charged my sister a very reasonable rate of $40/day. I provided all food.
oofa, sorry but my first thought was dang thats alot to charge a sister/neice...for $200/week I hope you were doing lots of activities with your neice that one would expect from a regular daycare....
Yes your sister would have learned the hard way that at a regular daycare you pay if you are there or not, but maybe thats why she was thinking it would be different with family?
Granted I pay $245/week for a great daycare, but my son has dance class, music class and karate, gym time, library time and playground time on nice days...and no tv time...
