I'm unsure what to do; woman I help with 2 yr. old, has waited till sometimes that 'day' to ask me to sit- she had said the week before tentatively for that day, but then txts me an hour before she needed me. Im uncertain if she might do that tomorrow again, ask me to come in in 2 hours, (b/c she had said she 'may' need tomorrow).. what would you do? Say no, or say yes perhaps or say you needed more notice ?
