It is not entirely unheard of to have children in one’s twenties. Â I’m 27. Â By this time in my dad’s life, he had two kids (me and my sister). Â It is not as common to have three sons all over the age of 14 at this point in one’s life. Â In fact, I hope it is super uncommon. Â Thirteen year olds should not, as a rule, have children.
