You become an adult when you get pregnant and if you can't be an adult about it, you shouldn't go on to raise a child.
Regardless of your age or anything else, your life absolutely must revolve around your child 24/7. That doesn't mean being attached at the hip, it means that for every single choice or decision you make, your first question to yourself needs to be "how will this affect my child", whether that's career choices, financial decisions (e.g. taking out credit, moving, buying a house or car etc, buying yourself new clothing/home decor/non essentials), childcare, plans with friends etc. My baby's dad has only recently started having her overnight at a year old, the choices and plans I make when she's not with me still revolve around her. Yes it's my time for a break, but I also choose not to do anything stupid, leave the area or get hammered etc because should she need me or something happen to her dad, I still need and want to be fit to parent, regardless of whether it's my time to have her. That's what being a parent is about, and if somebody can't handle that, they shouldn't have a child. I don't care if you're 14 or 40. YOU choose to have a child, YOU choose to take on the responsibility, YOU make the conscious decisions, and if you can't handle all that comes along with it, including swallowing your pride and taking advice, allowing health professionals to take the lead etc, you shouldn't have a child.
