I'm sure this has been asked before, and sorry if I missed it, but can anyone recommend a good lightweight stroller for my dd who is just under 40 lbs.? She still likes to ride in the stroller (she's 4) and I'd like to get a new one before we go on vacation. I think I read about the Kite Lite? stroller by Graco somewhere. Would this be good for her size/weight? Thanks for any responses!
