OK so the last thread has gone a little, um, mad, so I'll just ask about my own situation instead of highjacking.
We are going on a cruise next week. My DS is 2, 36" and 35#. We are taking a taxi, most likely, from the airport to the hotel then to the ship and back. My DH wants to know what the point of the CARES harness is since DS has to have his own seat anyway why can't we just put him in the airplane seat belt. Also I had found the the RideSafer vest and then saw today it is only for 3 and up? He is in the weight and height range of it. Dh much preferred the use of that over taking our amazingly heavy Radian to have it sit in a small ship cabin for week and be in the way.
Is taking the radian on the plane our only choice?
