You might find one on craigslist.com that is used and cheap enough. I have a cheap $15 umbrella stroller from Walmart that has a little bag on the back of it to put a few things in. I use it occasionally for my barely 4 year old who weighs 33 pounds. He is almost too tall for it (his feet can hang down on the ground if he wants to instead of keeping them on the foot strap); but for the money it is worth it for the few times I need it at the mall, etc. Also, if you only need it for the mall and zoo they have "car strollers" at the mall you can rent and strollers at the zoo to rent also. If you only need to use it a handful of times before she is able to walk better for long periods you might consider renting those too. Best of luck. C.
