I have the 24 hour rule and I think it was really nice of you to let that parent bring her child at 11am so she didn't have to use an entire sick day. Employers are getting worse and worse for letting their employees take sick days. But we have to protect the other children in care so we have to enforce our sick policies.

I breastfed my babies and my youngest would never take a bottle at all, however I would never have asked to feed her in my babysitter's home! This was back in the day when there were only babysitters and we had to return to work after 16 weeks so my baby was barely 4 months old. She was one of 'those' kids that caused great problems and cried all day for her Mom.

Anyway, I like playfelt's suggestion to give the child a little snack to tide them over so you can get them out of your home ASAP!
