typing one handed...
we have done it twice...once when dd was 6 months and once at 13 months. doing it again when she will be 22 months. it is no problem. you have every right to fly fc if you want. it is challenging to fly with a lap child anywhere on the plane. dd is a good flyer but one part of our last trip she wasn't feeling well, and was fussy from MSP-SEA. we got a couple of looks, and at the end of the flight, i realized that they lady who kept shooting me nasty looks had a DOG in her purse! yeesh, ok for her to have a dog in fc, but not ok for me to have a child. whatever.
one leg of the flight from DTW-MCO, there were two boys about 7 years old flying fc, and they were making a huge mess, kicking seats, throwing food...they were much more badly behaved-if they were mine, i would have been really emabarrassed.
on her first trip, when we stood up to exit, a woman commented to me that she wouldn't have known dd was on the flight because she was so quiet.
unfortunately, i think the most looks i got were because i was nursing on the plane! on several trips, i would get looks when i popped out the boob-doesn't bother me! i would rather someone get a flash of skin than have to listen to a baby cry because her ears hurt.
