Have you talked to your parents? The first step is making a plan and getting your support system in order. You need to find out what insurance is available to you (your parents can help with that).
You also need to seriously look at the best interest of the child. How will you afford clothing, diapers, food, carseats, furniture and basic necessities? That isn't including the other things that come along. For instance, did you know that dance classes, little league, swimming lessons all cost money? And there are fees at school every other week for pictures or a field trip. I'm just saying, if you cannot afford the basics for the child, how will you afford the other things that just happen?
Having a child is incredibly expensive. Daycare is a major expense. These are all things you are going to need to sit down and figure out with your parents or someone who can show you the bigger picture.
This isn't meant to be negative, it is realistic. TALK TO YOUR PARENTS!
