Hello!
I'm wondering since you're assuming that a newborn will mostly sleep through it if this is your first? Some are sleepers, but some aren't--until you meet the little one, it's hard to know. We planned to fly to my dad's b'day party when my daughter was a month and a half (direct flight from Houston to Ft Lauderdale) but ended up canceling because I just couldn't deal with getting ready and the thought of flying with her. I did fly with her to see my folks a little over a month later though. I think it's just hard to know how it will be/when would be a good time until you meet your baby. They are all so different, and in my experience it was a ton more exhausting and stressful than I ever could have imagined (though I definitely had the baby blues, a daughter who wasn't a great sleeper, and who didn't latch on--I pumped). I'm not trying to be a downer, but just give one mom's honest experience. I'm not planning anything with this next one until I meet her!
Good luck and congrats in any case! :D
