I thin the problem is that many people become parents without thinking
about it. I'm despairing with a professional colleague at the moment who
had children because "the biological clock is ticking". Now the children
are simply handed to nanny and the parent does nothing with the kids
except a good night kiss.

The same parent has "issues" with their own parents who behaved in
exactly the same way. Despite gentle prodding she can't see that her own
children will probably end up with the same problems (about parental
rejection) that she had.
