Hi. I have a 3 year old son with a form of Cerebral Palsy that causes his muscles and joints to be floppy / hypotonic (he still cannot sit up on his own). We are located in Canada and all the advice I have seen is for US seats. He is small for his age (wears 2t clothing), weighs about 28lbs and is about 34in tall. We are looking for options for a car seat that can be used easily for travel on airplanes as well as from in the car when he maxes out the weight in his current seat (First Years Tru Fit - 35lbs rf limit). The Tru Fit seem too wide for airplane travel. What seats have some recline when forward facing? Any that are good for airplane travel? We have a 2015 Honda Odyssey (8 seat model) and a 2005 VW Passat Wagon as vehicle options. We can use the Tru Fit in one and the new seat in the other.
