Older sibling group - court in Russia

Hi Everyone - My husband and I are in the process of adopting 4 siblings from Russia, ages 8 - 12. From what I understand, the 2 older than 10 years old will go to court with us. Has anyone gone through that? How does that work? How can the children not be scared to death? Also, any travel tips for Trip 2 -- "must-haves" to bring to ease the trip emotions, etc. for the kids? Thanks!!
