He's 20 months old and has a type of dwarfism.
He doesn't speak, but is doing well otherwise. Has just learned to walk confidently, plays imaginatively, can point, makes eye contact. He can't do as many things as my dd's could at that age (apart from speaking also things like those wooden puzzles, of the top off my head), but I'm not sure if he would be a candidate for portage or whether he doesn't really have enough problems to qualify?
