for our upcoming trip to WDW. In fact, I'll be right at the end of my first trimester. I haven't gotten nauseous with my last pregnancy or (so far) with this one, but I do get exhausted.
A few tips based on my last (non-pregnant) trip to WDW: take lots of bottled water & any comfort medications that you may already be using at home (for me, I go through Tums like crazy when pregnant), know the locations of the fruit stands and visit them for a healthy snack (they're pricey, but still reasonable when compared to other snack options in WDW), pack your own healthy snacks, plan lunch in a quiet area where you can sit-down and relax, and don't be afraid to tell the rest of your group that you need a break. I also highly recommed a nap right before dinner -- really gives me the umph to make it through dinner and on to a show afterwards! Also, wear comfy clothes with room in them and definitely some comfy tennis shoes with good support for all of the walking.
Know ahead of time which rides you'll probably want to skip. We plan to take our toddler on the kiddie rides together and then my husband will go on a few adult rides while my son and I head back to the hotel for a nap before dinner. (This worked well for us on a recent trip to
Disneyland.)
Basically, try to get lots of rest, eat healthy, be comfortable, and listen to your body so that you can give it what it needs.
Best of luck with your pregnancy!
