Strollers are usually classified by function: Full-featured strollers allow babies to lie flat, are suitable for newborns, and have good shock absorption but are heavier; lightweight, foldable strollers are compact and easy to store, suitable for short trips; and high-view strollers have large wheels and a high ground clearance, which reduces exposure to dust and exhaust fumes.

Babies have different needs at different stages: Newborns (0-3 months) need a flat lying space, so choose a model with a bassinet or one that reclines completely flat; for babies aged 3-12 months who can sit up independently, you can switch to a seated mode, paying attention to adjusting the backrest angle; toddlers over 1 year old are suitable for seated strollers, but ensure the safety harness is secure. Avoid expecting one stroller to last until your child is 3 years old, as babies develop quickly and their needs change significantly.

In terms of safety, be sure to check if the five-point safety harness is adjustable to ensure your baby is securely seated; for comfort, shock absorption is very important, especially on uneven surfaces, so consider models with springs or air-filled tires; additionally, the seat width and adjustability should match your baby's size to avoid it being too tight or too loose.

Lightweight design and functionality often require trade-offs: if you frequently use public transportation or travel long distances, prioritize models that fold into a compact size; if primarily for short trips, focus on shock absorption and spaciousness for comfort. Be sure to check if the folding mechanism is easy to operate and confirm that the weight is within an acceptable range.
