Well, you have to take into consideration the weight limit for the
LATCH system. I don't have my
LATCH manual inside with me, but I *believe* Honda's weight limit is 40lbs. So, if she is over that, you will have to use the Short belt path with the recline bar and the tether. As for overseas use, You could do a couple of things. If you want her harnessed on the place, you can check out the
Graco Nautilus; harness to 65lbs, then
booster to 100lbs--then you can use it as a backup when you get home. It will run you about $150. You could try her out in an Evenflo Triumph Advance (it harnesses to 50lbs), but you likely won't get any use out of it.
Another inexpensive route is to get a backless
booster, put it in a piece of check on luggage and use that when you are overseas.
If it were me, I'd get the
Nautilus only b/c it harnesses to 65lbs and I know I can use it in another vehicle later on. It is a larger, fairly heavy seat.
