Missing out on child's life?

Yes, get involved. Kids don't remember much before four years' old, so in future years the kid won't remember that there was a time before Daddy became involved.

He should go to court first and make sure the child is his. Then he should get a custody arrangement so he knows what days he can get the child. He should start slow -- meeting in the park while Mommy or a grandparent already known by the child is nearby.

If he wants to be a stable part of his child's life, then it's never too late. He would need to go to court and submit to a paternity test, and then he and his ex would have to agree on a visitation schedule.

Yes a child doesn't remember things the first few years of life anyways. He would have the rest of his life to spend with the child and see all the milestones they will go through and the child would have his biological father in his life

If mother didn't want him there then she doesn't want him there now.

Yes it us worth getting involved. It is not a n after of him and what he missed, but the child that deserves a father.

Yes get involved. It is a sad situation but you have to make the best of it. I know someone who didn't meet their dad until they were 9. 4 year olds don't remember much. This isn't about what the mum wants. The child is 50% the mans as well
