Congrats on the baby! As others have mentioned, it’s still early to guess how your wife will be feeling at that point in her pregnancy. One potential concern would be the possibility of exhaustion/energy-zapping that may hit her as she moves along into her third trimester. A lay-by-the-beach vacation is one thing, but lots of walking and sightseeing could be a bit much that late in the game. On the other hand, of course, maybe not. Tough to know in advance. My husband and I did a twelve hour flight from the East Coast to Hawaii in mid-February when I was 23 weeks and it seemed to be a sweet spot. Although the flight was long, I wore compression socks, moved around, drank water, had an aisle seat, and was generally comfortable. Also, we took it easy on vacation, which was our plan all along and I was feeling fine at that stage in the game. At 29 weeks now, though, I’d be a bit crankier. If she is still pretty comfortable and mobile, you guys will likely be good to go. But if planning something slightly earlier or being prepared to take it easy on sightseeing is an option, I’d keep that in mind to be on the safe side. Good luck!
