Whether you've already got a couple of kids or are just adding one more to the mix, a double stroller is a must-have for multiples, especially under the age of five. And if you think you don't need one, trust us—you do. Even when they know how to walk, they really won't want to on long days and extended adventures.

Deciding on a double stroller for a 3-year-old and a newborn in 2026 depends heavily on your lifestyle, but for most parents, it is highly recommended. While a 3-year-old can walk, they often lack the stamina for long outings like zoo trips, shopping malls, or theme park visits. A tandem or side-by-side double stroller allows the newborn to lie flat (often in a bassinet or car seat attachment) while providing a "safe haven" for the toddler when they inevitably get tired or overwhelmed. If you live in a city and do a lot of walking, a double is a "sanity-saver." However, if your 3-year-old is exceptionally active and you rarely do long walks, you might opt for a single stroller for the baby and a "ride-on board" (glider board) for the older child. Another popular 2026 alternative is baby-wearing the newborn in a wrap while using a lightweight umbrella stroller for the 3-year-old, offering maximum flexibility.
