How old a baby can use a stroller

There are many dads and nannies who begin to buy various baby products before the baby is born, and the baby carriage is one of the mandatory items among many baby products. We all know that it is convenient for babies to take their babies out, but the selection criteria for strollers are different for babies of different ages. Let me introduce them to you.
First of all, the baby within three months of age is particularly delicate at this time, and the baby's head is still soft. Long term use of the stroller is not conducive to the baby's head development, so it is more appropriate for the baby to lie flat after three months.
In addition, it is better to choose a stroller with high landscape, which can prevent the baby from being polluted by automobile exhaust gas, and can also let the baby's eyes see a higher and farther landscape, helping the baby's vision development. Moreover, the wheels of the stroller must be very sensitive, which is also one of the standards to check whether the stroller is safe; The fabric in the stroller should be made of cotton or polyester, which will not dye and will not harm the baby's skin.
Babies of different ages need different strollers, for example, babies under six months should choose a stroller with high landscape; The baby aged one to three can choose a medium-sized stroller; Older babies should choose portable strollers.
