Ah Scalder....
Time will heal some of this, but our intense kids tend to react intensely!
While you were traveling, he probably got used to 'seeing and learning' new things all the time. It's going to be hard for him to settle back into routine.
As always I recommend 'upping the ante' as far as excited, factual, verbal praise - see the book 'Transforming the Difficult Child Workbook' by Lisa Bravo for more details.
It is also true that vacations lead to developmental leaps and developmental leaps lead to tantrums.
I would keep those reasonable limits in place and as clear as possible, and try to calm and sooth yourself "emotional earplugs?" while the needed tantrums fly.
Love and More Love,
Grinity
