I'll be flying back to America next week (at 23 weeks and 26 on the way back) with my 6-year-old daughter. We have a 2hr drive to Manchester, 1-2hr flight to Munich, 9hr flight to DC and 4hr drive home. It's going to be a long, miserable day. My plan thus far is to pack lots of snacks for both of us, drink lots of water (which will keep me running to bathroom and keep the blood flowing), flight socks and some calf exercises (rotating ankles, wiggling toes, etc.). Any other useful tips for flying pregnant? I already get tingly feet and swelling if I sit still (or stand) for too long...and back discomfort. My daughter is an excellent flier so I know she will be a big help.
