Oh brother, where art thou?

Woke up to Addi crying at 6 this morning. That is way too early for my kids to ever be allowed to wake up. I walk in and she says "MOM! I can't find my brother!" So I had to lift her up out of bed and show her he was just snuggled into a corner of his crib she couldn't see. She calmed down and got really tired and went right back to sleep. So my question, was she worried about her brother, or worried that her brother was getting to do something spectacular that she wasn't?;)
