Sarah is in love with Craig right now. It's been in development but was certainly a problem last week when he went to Ulsan for the night and Sarah would not go to bed because she wanted "Daddy! Daddy! Daddy! ((sob, sob, sob)) Daddyyyyyyyyyyyy!"
I think I am on to her though and she really just wants what she doesn't currently have because when Craig gets home from work, although she is super happy to see him she still wants "Mommyyyyyy!" most of the rest of the evening.
