What do you think about other moms approaching your sitter to work for them? My sitter works for me part time when I work. The moms are SAHMs. I have one optional day with my sitter a week. I had a work emergency and called her the night before. She was booked, with one of these moms, who wanted prepare for a party that night, and then sitter said she felt bad but both the moms had asked her not to tell me. I had wondered why my optional day was all of a sudden gone. This seems really strange to me.
