Separation Anxiety Attack

Time is moving so fast. I can't believe that my kids are teenagers now and in 16 days they will be traveling on their own. I am sending both of them to my sis-in-law for the summer. They are going to be there for 5 weeks! Are they ready to be on their own? Or should I ask, am I ready to let them go??? Don't really have a choice now since their tickets are already booked.

My daughter is graduating grade 6 and my son is graduating fro middle school, grade 9. So this is sort of their graduation gifts. The house will be too quiet once they leave... I hope they won't feel homesick. Just thinking about it, I am sure going to miss them!
