So I have an autistic 22 month old who does very well sleeping in his big stroller but not so much in an umbrella stroller. It is fully collapsible.We were planning on taking the big one for that reason and also because it has the big wheel which is easy to drive in sand etc. As I've been reading posts about strollers, everyone is saying that I will have trouble walking in the hallways and in the elevators etc. I want to bring it to make my life easier not harder. What do you think?
