Michelle,
I think that this is very personal, I have friends who have left their children from the time they were small babies. Personally, I have never left any of my children for that long (I have 5). Last month my husband and I went to Kentucky for 5 days. This was the first time I had EVER left any of my children for more than an overnight at grandma's. We took our youngest with us because she was still nursing (16 months at the time). I really missed my kids and never could have left my baby that long. My daughter who is 3 was quite angry with us for a very long time after we returned. She would scream "I hate you" (which she never did before)...so I believe 5 days was too long for her. When they are too little to understand that you are leaving for a short time and will return, I think they are too little to leave. We sure paid for leaving our daughter for that long. She was miserable and nasty to us for about a week after we returned. The boys are all old enough to understand and while I won't say it was easy for them, they definitely handled it much better than my girl.
I know that you want to get away, but I would really think long and hard before making definite plans to leave my baby for that long. It is a big deal, and a nanny is not mom and dad. Maybe you can take the baby and the nanny, put them up in a different room, and then see your baby when you want, but have private and free time when you want...the best of both worlds. Of course it would cost more, but it would be worth it to me.
Let us know what you decide.
