We are planning to do an international trip with our baby around that time. Ideas include Ireland, Algrarve Portugal (both short flights) and Japan/Philippines (longggg flight). I’d say go where YOU want to go and see how the travel shakes out. Build in days for recovery after travel.
I would say this is a great time to fly before they learn they have legs that can run. !! So in my opinion definitely take advantage of a flight right now!! I have 2 under 2, my husbands from Ireland so we're traveling back and forth often from there. Especially with a night flight it's not to bad!
We went to NH when my son was 2 months old, it was nice laid back and the white mountains are about a 3 hour drive for us. When he is 9 months old we are actually going on a cruise, there is cruises out of Boston that go to Bermuda and Canada. We did the Canadian cruise with Royal Caribbean before our son and overall have been on several cruises and really enjoy it. So I’d say a cruise! There is so much to do, laid back and very little planning
