Is the reason for not traveling with a baby because he is too young to remember anything?

According to a survey of people around me, most parents choose to travel with their babies when they are about four years old or older. The reason given is that when they are too young, they won’t remember anything from the trip. But is this really the case? Most people’s first reaction is indeed “yes,” but when asked again, they often add, “He’s too young to understand, and it’s just too tiring to take him along.” I think that might be part of the reason as well.

First of all, from the moment a baby is born, or even during the fetal stage in the mother’s womb, as soon as the nervous system begins to develop, it means the baby needs stimulation from various environments to help it grow and mature. For example, a pregnant mother can listen to pleasant music to stimulate the baby’s cerebral cortex. After birth, the ways a baby can perceive stimulation increase significantly—through the eyes, ears, mouth, nose, hands, and feet. Therefore, diverse stimulation is indeed necessary. For instance, we can give the baby colorful toys to play with, let them listen to nice music, start introducing complementary foods at six months, and gradually expand the variety of foods. If possible, taking a baby under three months old out to see the outside world is also a good idea. Going to the neighborhood downstairs every day is a great option. Usually, there are plenty of green plants, not too many people, and the air is relatively fresh. However, some babies don’t go outside at all within the first three months, simply out of fear of bacteria and viruses in the external environment causing illness. Honestly, that’s quite laughable—do you really think there are fewer viruses in your home than in the outside world? Moreover, babies under six months have antibodies passed on from their mothers, giving them very strong resistance.
