Mom of 4...EEK

I am headed to my sisters house to take on the challenge of playing Mom of 4! She is headed to Cancun and I am nice (or crazy) enough that I said I would take care of her kids. This should be fun.....Her daughter is 6, and she has two sons that are 4 and 19 months. Throw my 14 month old into the mix and I am looking at a crazy week. I am thrilled to get to spend that much time with my niece and nephews. Normally I only get to see them on quick day or two long trips. I have always said I wanted 4 kids....so we'll see if I change my mind by Monday! LOL.
