All I can think about is those Mickey rice crispy treats because they look so marshmallowy and DELICIOUS. Yum!! I hope your MIL is excited for the trip!! I like the bag you guys got for her.
I'm sorry you'll have to miss out on the safari at AK! You might end up seeing things you'd ordinarily miss out on because your focus will be on things other than rides...I always say I'm going to spend a day just walking around, but of course that never happens!
My favorite part of OB appointments was hearing the heartbeat

Mine were wigglers, too...one of my favorite pregnancy memories was when we went to see XMen in the theater. I was sitting next to a boy who was about 8 or 9, and X rolled or something and you could see the the bulge of his elbow or leg or whatever it was move across my stomach. That kid's eyes were as big as saucers, it was so funny! His mom was leaning over asking us a question, and she noticed and laughed and laughed. I'm pretty sure the kid thought I was definitely a mutant, or at least harboring an alien, LOL!
And if you have a girl, you can take Jay's approach from Modern Family when Lily tried to run at
Disneyland...put her in those plastic princess heels, and she won't be able to move very quickly
I hope you start to feel better soon and are 100% by trip time!
