YEP, I'm glad it's Friday too!
And Diana, I can tell you that I would not do well at all keeping a two year old five days a week. In fact, I just don't know if I could do it. I have a two year old granddaughter, who is VERY attached to her mom so I only babysit occasionally, and I always go to her house where she has all her toys (and it is two-year old proof - which my house is NOT). Anyway, after only a few hours, I am pooped!!! I don't know if I could do it all day everyday. There is a reason why older women don't have babies!!!
I admire you for doing this for Karlie - I know she needs you, but I also know it is very hard on you too! Take care of yourself.
