All strollers have a recommended weight and height limit. If your child exceeds the limit, the frame may not be strong enough to hold him. Strollers with fully reclining backs have weight limits that generally top out around 50 pounds. Depending on the child, this type of stroller can serve you well from birth through about age four or five. Umbrella strollers usually have a maximum weight limit of about 40 pounds, but be sure to check before buying.
