What age do you think is the most appropriate age for a woman to have her first child?

I think at least 25 or older because it’s a fact the rational part of a teen's brain isn't fully developed and won't be until age 25 or so. In fact, recent research has found that adult and teen brains work differently. Adults think with the prefrontal cortex, the brain's rational part.

Also I think most 18,19,20 and 21 year olds probably don’t have that much money in the bank to raise a child properly.
