I came across these online while searching for some sort of travel activity pack for my dd for the plane when we go in November (she'll be 29 months old). BTW, if anyone knows of any sort of activity type of pack that's already pre-made that I could buy somewhere or order online, I would appreciate it! Anway, I found this stroller and was wondering if anyone has ever used one. If so, did you like it? This one only goes up to 30 lbs., but another one by Kelty goes up to 50 lbs. Thanks for your input!
