Many couples plan their lives as a mathematical calculation. I want to have so many children and have such a difference in age. But, sometimes, circumstances cause us to change our mind on the fly.
Having a child must be born from the desire and desire to be parents again and give a brother to the son or children we already have. Beyond little or much difference, each child needs to occupy their space within the family structure.
Like everything, little or much age difference between siblings, has its advantages and disadvantages.
When they take a little age difference they share games and maintain more fluid relationships because the needs are practically common. The mutual company enriches them and they have more complicity. From the point of view of parents, let's say resources are saved. They concentrate the work of raising children at a certain stage of life. Diapers for everyone, bottles for everyone, etc. Although multiplying by two (or three) the needs of a small child can be exhausting and the fatigue is much greater.
When it takes many years (I speak of more than 6) for parents it can be a great effort to start over. The child enjoys his stage as an only child for a longer time, with its advantages and disadvantages. The elder with several years of difference often becomes the protector of the younger brother, serving as a guide and support.
Among the disadvantages, they barely share games and if the difference is very large, everyone will need their own room. The elder may suffer an identity crisis, having been an only child for many years while the child runs the risk of being very spoiled.
Anyway, I hope that if you plan the arrival of a little brother, the decision is a product more of the heart than of mathematics.
