I live in the same area and looking as well. Fortunately, I will have 3 months off with baby but I am looking at part time nanny to just help out a few hours 2/3 times a week when I do return to work.
You know I was at Beeman park the other day and saw a lady posting up fliers for nanny work. I don't know how reliable that is though. but maybe next time I'll ask a few of the moms there if they have any recommendations. I'll let you know
