There are certain things that parents require when taking care of a baby and while a baby stroller is not completely necessary, it is definitely a convenience. Strollers provide a means to exercise for mom, make travel simpler and they allow Baby to explore the world.
Soon after the baby is born Mom should start exercising to help speed recovery. Walks give both the baby and Mom fresh air. Walks with the baby stroller also let Baby see the big world around him.
A baby stroller can also make travel much easier for parents, especially if the stroller folds up for storage. Many strollers can be checked at the gate when flying so that the baby does not have to be carried through the whole airport. Visits to parks and zoos are also easier when a stroller is there to tote the baby and all the souvenirs.
