Lastly, try to observe the simple fact that you probably need two scooters as an opportunity, not a burden -- even though it is an opportunity requiring more outlay of money. While a umbrella stroller is fantastic for afternoons in the city, it is useless for running on a course. Likewise, a jogging stroller is excellent for a morning through the suburbs, but a poor choice for surfing the narrow aisles of a store or for carrying onto the subway. If storage area or space constrains one to one stroller, then just make sure to find one that is flexible.
Then think about the kinds of actions you see yourself and your kid sharing. If you're a avid runner, then a jogging stroller is a terrific idea. If you are always off and on trains or subways, then an extra lightweight and lightweight folding stroller is a must. If your plan is to make your child with you on all of your errands, look for additional storage capability underneath the stroller. And in the event you are going to be in and outside of your car all the time, ensure that your stroller and car seats are compatible.
As for selecting the most appropriate stroller(s), start with the basics. How big is your kid? For how long will she need extra support and padding around her neck and head? Have to be lying flat in a bassinet? Could she feed herself from a tray yet? And so forth. Start by considering your child's size, needs, and abilities, in other words.
For your record, you're not going to find any tandem/double strollers recorded here. That isn't because I really don't like double strollers or even because lots of good ones exist, but is only because many manufacturers which make a nice single stroller also offer double/tandem units. If you're partial to a brand or sold by some of the things here, take a look at their multi-kid options.
