answer:Yes, I worked with two guys. One his parents had him when they were in their 40s. He seems to have suffered childhood fine,. He grew up on an island though, kind of cut off, The other, an only child, came out of childhood determined that his children would have siblings. Both grew up to be fine men. I have two friends that had their child, an only child, in their 40s. He used to joke that he felt like her grandfather when he picked her up at nursery school, but it did not matter in the greater scheme of things. She did not suffer from it.
