Sounds like things will be okay once everything settles down. It's great that the dogs are getting along okay. Tobagganing was a really wonderful idea on Alex's part. That will tire the kids out AND they get to have some fun!
And yeah, we do live in a huge country. I lived in B.C. for awhile and it was hard to get used to the time change when I called home! Have you ever been to Newfoundland?
