Getting ready for the first big trip!

Russell and I will be leaving early Tuesday morning for our first visit to meet Emily. I have been getting everything ready for a week now. She will stay with us at our hotel so that means packing everything a seven month old baby needs, and yet we have not met her and don't really know what she likes or dislikes, her schedule, and exactly what size clothes she wears. We were told that she is around 20lbs. so I am taking different sizes of clothes just to be sure.
