Hi - We are moving to E Africa with our 19 mo twins and taking car seats with us (lightweight kiddy pro seats). I can't decide if taking the seats on the flight will make life easier or harder. On the plus side, they will be restrained, hopefully sleep in them, and less stress on my back (which is bad). On the down side, they will be so cumbersome to take through security etc plus double buggy and everything else. My husband is convinced we should put them in the hold, which raises another concern - will they get damaged there and how to protect them? Any other advice for flying with twins much appreciated!
