Motion sickness
How unfortunate that you seem to have inherited this from me. It has only happened twice now, but neither time fun at all. The first time was on the flight to Iowa. The second was yesterday.
A nice 72 degree day in December! We packed up to go to the zoo, which was in itself a chore...so I wasn't too happy to get all the way there only to discover that my wallet was at home. So, I swung the car around and went back. I ran inside, grabbed the wallet and headed back out the door. As we pulled into the parking lot, you started saying "uh, oh! uh, oh!" and then it happened. Puke everywhere...you, your hair, the car seat...disaster! I don't know what was upsetting you more: the tummy trouble, the dirty clothes, or not getting to go to the zoo like we had talked about,
Of course, my first thought was that you had a bug, but after a nap and some cheerios, you have been fine for 24 hours...must have been the hot car ride. No more of those for a while!
