THAT'S MEN:Nothing is as cut and dried as it used to be, when times were simpler and fathers knew their place
THE CONCEPT of fatherhood grows more complex by the week.
The case of the lesbian couple who were successful in the High Court in fighting off a bid for guardianship and access rights by the child's biological father provides one example - albeit not a common one - of this growing complexity.
Recent stories from Britain which featured single mothers with children by several fathers provide another.
In Ireland, the significant number of births outside marriage means that, in many cases, the men the mothers in question eventually marry will not be the biological fathers of at least some of the children in the family.
Divorce, too, means that the role of father becomes blurred when new families form.
Once upon a time, it was all so much simpler. A father was a man who was married to a woman who gave birth to their children and stayed at home and minded them while the father supported the family.
When people stepped outside that basic concept by getting pregnant outside marriage, matters were put to rights, either by a hurried wedding or by shipping the mother off to a mother and baby home, and the baby to an adoptive family. In this case, the father remained invisible and - to outward appearances at any rate - untouched by the whole thing.
Well, that has all changed, and about time too. But are fathers up to the demands of these new roles (I will get back to the issue of same-sex couples later)?
I haven't had to do it but it strikes me as a tough job to take on where a man marries, or lives with, a woman who has children from a previous marriage.
On the one hand, the man is not the children's father. On the other hand, he will inevitably find himself taking on some of the "care and control" aspects of a fathering role.
If a young teenager who was meant to be home at 9pm doesn't turn up until after midnight, it would be a poor show indeed if he shrugged his shoulders and declared it was nothing to do with him.
Similarly, if a child from the previous marriage was being bullied at school, it would be despicable of the mother's new partner to wash his hands of the whole thing.
Suppose we are not talking about children from a previous marriage or from one previous relationship. Suppose, as in those British cases that have been in the news, there are several children with several different fathers.
Is any subsequent partner up to fathering all of these children? I know there are other fathers in the vicinity, so to speak, but the partner is "on site" and he is the one who faces the most immediate challenges.
Frankly, I don't think any partner is up to facing those challenges in this situation unless he is an extraordinary human being. Most of us are not extraordinary human beings. Most of us would fall down on that particular job.
In same-sex couples with a child born either through sperm donation or through surrogacy (in the case of men), the situation is either more or less difficult, depending on how you look at it.
In the UK, as I understand it, if the child was conceived from sperm donated through a licensed clinic, then the biological parent has neither rights nor obligations.
If the child was conceived through a private arrangement, the biological parent may have rights and responsibilities - a man could be forced to pay maintenance for the upkeep of the child, for instance.
In the same-sex couple, will one partner take on the role of father in an emotional and psychological sense? I expect that is how it will work out. I hope so - if I were a bold child I wouldn't want to have two mothers angry with me at the same time (sorry, girls). Oh alright, for the sake of balance, two fathers either.
So, fathering has become as complicated as it could get and we have a lot of work to do to figure out how to handle it.
A little courage on the part of policy-makers would help. As would a determination to deal with the world as it is - and not as we think it ought to be.
