Find Alternate Methods to "The System" at All Costs!
Having read your post, I too am reminded that I myself was once young and Married a week after my 17th Birthday. My Ex-Wife and I were parents of 2 beautiful children before we were 18 years old. It was rough back then, but nothing like it is now, with all the new "Best Interest of the Child" laws.
Whatever you have to do, (within the law of course), that doesnt ever put your baby at risk of coming into contact with any State Agencies who have access to court orders, judges, or claim to Act in the best interest of the child, is what you have to do to survive.
I strongly urge you to step up to the plate and protect your child, with or without the father involved, as the bond between Mother and Child is one that is Protected under the Constitution of the United States of America Itself. Get your moms help, and remember She Loves you like youre going to Love your own baby. Keep a record book of whatever she does for you so you can repay her one day, (Also you may one day need it to protect yourself and your child from being legally seperated by the courts). Work, play, and love your child with all that you have to give as a mother and a woman, believe me, it will all change once you hold that tiny baby in your arms for the very first time.
Also I caution you now and well in advance, avoid "The System" and all it's entrapments and snares, as they will be used against you in a court of law one day if you do not. Avoid those who preach "The Best Interest of the Child" at all costs, because there is Big Money in the United States today in the Removal of Children, and termination of the Mothers Rights, (Meaning you are less than a stranger, they are protected from you), and Adopting out these children to other "Types" of families, and by types I mean families who could never naturally have children together.
I wish you the very best in this life and may you and yours be ever happy and together.
