We're driving down to disney in Late November. Right now the boys weigh a combined 94lbs (just finished growth spurts). My oldest has mild CP, severe asthma, and has seizures when he overheats so I need a stroller handy for him. My younger is only 3yo and has sensory needs, so he needs a quiet place to sit for decompressing. Last year we bought a sit and stand for the trip there, and it was perfect, but alas - perfect doesn't last forever. So now I'm on the quest for a larger double stroller. That will hold closer to 120lbs, but 110 might work. I don't want to spend a crazy amount of money, and would buy used of course. Thoughts - suggestions?
