My sister-in-law is expecting twins, and she was asking me about double strollers. I figured my opinion wouldn't be worth as much as the opinion of several moms, so I'm setting up a poll. Leave a comment with your opinion of the best stroller. What are the pros and cons of a double stroller? Are double strollers too bulky? Any favorite or least favorite brands? What about the ones that can be used with car seats? Let me know, and I'll pass along the info. Thanks for the help!
