The right age for children
While modern science and medicine will say that somewhere around early 20s is a biologically good time to start family planning, that doesn’t mean prospective parents are ready for little ones at that age. The fact is, child-rearing is probably the most challenging, stressful activity a marriage or parent can go through.
Because people are different, and even more so with a partner or spouse, some people may very well be ready to manage four children at 25 while others hit their prime in their mid 30s. So many issues come into play beyond just physical capability to bear and care for children.
A good child-rearing candidate has the ability raise a child from newborn baby to adult either as a partner or as a single parent and can provide the financial, educational, mental, and physical support and protection needed. This candidate can be in her or his 20s, 30s, 40s, and even 50s. Age is not so much a factors as is the ability to provide all the elements of care.
That said, those in their late 30s, 40s, and 50s will have more physical challenges caring for children. Obviously, there is a higher risk of miscarriage or genetic defects the older a parent gets when trying to have a child. However, older parents tend to have more maturity and resources to use that provide a better child-rearing environment than someone in their early 20s.
So, bottom line, a good candidate for children depends on a lot of different issues coming together in the right mix. That said, the most important factor is the ability to love a child more so than yourself. That ability tends to take care of everything else in many cases.
