So in an effort to keep the absolutely misery (both his, mine, and our fellow passengers') to a minimum, I decided to give him some Tylenol and Benadryl before we took off. Honestly? Best.Decision.Ever.
At one point during the descent I started to feel anxious and panicky because it felt like someone was stabbing me in the sinuses and eardrums. Awful. And dealing with the pain I had while trying to calm a screaming baby who was also getting stabbed in the sinuses would have been no fun.
More info on Kiernan's big adventures later. Promise.
