A single-seat stroller could work just fine for your family's needs. However, when juggling two small children or a toddler and an infant, a double stroller can be very useful. Both of your kids will have a comfy and safe place to sit while you're out—without requiring you to hold their hands or carry them.

Deciding on a double stroller usually comes down to three main factors: the age gap between your children, their individual stamina, and your lifestyle. If you have two children under the age of three, a double stroller is almost a necessity for any outing longer than a quick trip to the car. Even if your older child can walk, they will often "hit a wall" during long excursions (like a day at a theme park or a zoo), and having a dedicated seat for them prevents you from having to carry a heavy toddler while pushing a baby. You might also need a double if you frequently walk long distances for exercise or errands, as it provides a secure "hub" for both kids and your gear. If your children are further apart in age (e.g., a 4-year-old and an infant), you might opt for a "Sit-and-Stand" stroller, which is more compact but offers a platform for the older child to hop on when tired. In 2026, many parents also consider "convertible" strollers (like the UPPAbaby Vista or Baby Jogger City Select) which start as a single but can be expanded to a double only when needed, allowing you to "test the waters" before committing to the larger footprint of a side-by-side or tandem double stroller.
