My main thinngs are ease of use, my children's comfort and won't make me push too hard to move it. Ive been looking more toward the Graco ready 2 grow that both boys will fit in. Its not a bells and whistles one but it has some noce features I like. The back seat can either be used for my new baby's car seat, as a regular seat for my 2 ur old, a jump seat or standing platform. My youngest one's car seat can go on either. My biggest concern as stated is pushing the silly thing. I don't have the muscle in my legs to push a stroller that doesn't want to move. Also the fact that I need a cane so it needs to support my weight. This was the best place for me to ask this and hope someone had an answer. I think I need to go test drive some strollers and see what works best for me.
