We have had an au pair for a month or so now. It was my second child's first birthday and she sat in her room all day not venturing out once. I must say I was perhaps expecting her to come down and sing happy birthday with us and the grandparents or even to get a card. Am I expecting too much? It was one of her days off. This is my first au pair experience so would be grateful for any guidelines on how much to expect her to integrate with the family.
