i was wondering if anyone had any tips/suggestions for flying with a child.
Like another said, know now that you're not going to be relaxed.
We took DS at 17 months as a lap child, from Seattle to San Diego. My arms were sore for DAYS. I arrived exhausted, circles under my eyes, flustered, sweaty, and miserable.
DS was heavy, big, tall, and squirmy. He slept for about half an hour after nursing, and while it was nice to have him sleeping, I had to hold him in ONE position so as to not wake him. He's normally not that fussy about sleep, but I was NOT going to risk it. Also, I'm short, and to make my lap level I had to be on my tiptoes, so you can only imagine how my calves felt.
Also, during the flight, I realized that if there was severe turbulence, there would be no chance in Hades that I could hold onto my kidlet, and he'd go flying. Where would he hit, who would he hit, how damaged would he be, how damaged would a person that he might hit be? How hideous would it be, if there were severe, no-warning, turbulence, and my kidlet was hurt or killed, because for that trip I felt too broke to pay for his seat and put him in his carseat?
Those are the feelings you need to prepare for.
WILL you have those feelings? You might. You might not. I HATED having those feelings, having NOT thought about it beforehand, hated being surprised by it. I hated being surprised at my exhaustion, at not having thought it all through. I also hated being on that trip, having NO extra money to buy him a seat on the way back (note that our carseat was checked through...it was there, for the land portion of the trip), and dreading that trip back. It was really a negative experience for us.
DS aged out of being a lap baby by the time we had our next flight from home, but I swore I would never do it again.
