Tough situation. I don't believe they should have separated this boy from his baby to begin with. That's a permanent decision that he could not possibly make understanding everything, his parents should have stepped in and urged him to keep the baby and help strengthen the bond between him and his baby. But that did not happen. At this point, after all that has happened, he should be thinking about what will cause the least amount of stress or burden to his child. I do not think it is wrong for him to reach out to his child, and if the "child" were older I'd say it is one thing to find them but since the child is so young- being in your 20s is still very young, and many people in their 20s are still living with parents or relying on them in some way- so I think the reaching out should be to the people who have actually raised the child (even though the child is not underage any longer). He could reach out to THEM, not the child, and explain that he really wants the opportunity to get to know his biological child, perhaps cushion it with a statement such as I'm not trying to take away the mom and dad she has, or to take their place? All of my opinion of this changes if it is another family member that raised the child. If it was a family member of his, then, no, he should be able to be more upfront about it and not feel like he is the keeper of some guarded family secret. Best wishes, OP, it's going to be tough however it goes.
