Seeking a reliable babysitter for my preschool-age grandson 2 days a week

We are in need of a reliable part-time sitter for our 4yr old grandson. Our daughter works full time and needs the support with child AM drop off (7am) and evening p/u (5:30pm) and provide snack and evening activity at his home. Daycare heathens is a language immersion daycare and is less than 10min from home in South City. We initially need 2 days/wk, but are willing to make it mutually beneficial to find the right person. If you're able to provide any sick child care to help out Mommy out sometime, let us know! We would really like to start care THIS MONTH.
