Title says it all, mostly. We're going to need something for an infant and a two year old, and are looking for recommendations for double strollers for general urban use (sidewalk-subway-bus, or are we asking too much) which also travel well. We currently have a single Maclaren Triumph which we like a lot, except for its tendency to tip over backward when the child is removed.

Also, if you travel with two young kids and don't use a double stroller, what is your preferred solution?

Thanks in advance,

Michael
