My son has gotten a 16 year old pregnant she is about 6 months along. She wants the baby for now but her mom wants her to put it up for adoption. My son wants to raise this baby with my help of course (which I want more than anything) my first grandchild. What do we need to do to establish his rights for this child? My son loves this girl and wants to marry her some day but he also wants her to finish school and go to college like she planned.
