I have firsthand experience in teen pregnancies as I became a mother at 15. I was enrolled in a teen moms program through my hospital (in NJ at the time) which was awesome! The program helped schedule doctor visits, childcare classes (which I highly recommend) and state assistance with Medicaid, WIC and food stamps. I'm a very independent person so I was against the state assistance until I was somewhat forced to enroll but I'm glad I did because I had no idea how much help it was. I was not your "typical person working the system" because I had a job to help support my daughter and I finished h.s. on time, graduating with my class. Try finding a similar program for your daughter.
I have no experience in attachment disorders but I can suggest that you support her in every way you can...my mother was an awesome support. Let your daughter be a mother even though you may not agree with how she parents...my mom stepped in when she thought it was necessary and even though she was only trying to help, it was frustrating and sometimes made me question myself as a parent. Allow the baby's father to be involved...my mom wasn't crazy about my daughter's father but she bit her lip and offered simple advice which allowed me to make my own decisions.
Being a young mom is one of the hardest things I've ever had to go through but I was determined to prove to the world that I could do it and today I have a lot to show for it so please don't ever let her think she can't do it because I'm living proof. If your daughter ever needs someone to talk to who knows exactly what she's going through, then PLEASE give her my email address and we can chat via the internet or phone. I wish her all the best and I welcome her to contact me. If only I had someone to talk to 15 years ago who knew what I was going through...
