I think some people mature more quickly than others, so for one specific person, being a husband at 19 might be okay while for others, it's too soon. With parenting, it's the same thing. Being mentally ready to be a parent comes at different times for everyone. However, I will say that I've never met a 19 year old that I thought was ready to have a child, or one that said they didn't regret having one that young if they'd already had one. I think when pregnancies happen accidentally, someone that age can make it work because they have to, but I don't think they should get pregnant on purpose that young.
