Do you think for young men there is a contradiction in telling teens to give up their baby for adoption and walking away from their children?

I know a young man who got a girl pregnant while they were in high school. He was raised in a household where abortion is not an option and so was she. The girl decided to keep the baby, and he barely knows his son who is now 3.5 years old. His father (the grandfather) is very unhappy his son is seemingy dissinterested. His son will be finishing college soon, and the career he is focused on will probably take him out of state for the first couple of years. His father thinks he should not consider a career that takes him so far from his child.

But, I was thinking, if the baby is well cared for, how is that different than giving the baby up for adoption? Especially in the mind of a young person.
