Having four children by four different men is in my opinion, shocking! Now I'm in no way saying it's ok to call someone a 4 x 4 but seriously, what kind of woman allows herself to become pregnant so many times with so many men. It's distasteful, and if I'm being honest it's not fair on the poor children involved, having multiple fathers, grandparents, aunts, uncles etc, I imagine it would be quite confusing
That's the issue, you only imagine it would be confusing. For most parents and their children it won't be confusing at all.the vast majority of parents are reasonable decent human beings who are quite capable of organising things in a way that makes it not upsetting or confusing.
What kind of woman becomes pregnant 4 times when different fathers are involved? Hmmm it's quite hard to generalise but I should imagine that perfectly normal women who want 3+ children and are perfectly capable of effectively parenting those children but for what ever reason do not remain with the same partner for life do.
The main difference between you and most of them is they want more children and do not spend their adult life with the same partner. I should imagine that in many other aspects of their lives they are not unlike those women who do wish to stay with the same partner for a life time and don't want more than 3 children.
I do understand that relationships breakdown and that later down the line a new couple will meet and they will maybe want to go on and have a child together, this is perfectly understandable and in general would be deemed by society to be acceptable. But for a woman to go on and keep getting pregnant by different men and not learning her lesson is I'm afraid, not acceptable
Perhaps she did learn a lesson. A very basic one. Sex causes babies in order to have a baby you usually have to have sex it's not unreasonable to imagine that could be the end goal and it's also not unreasonable to assume that it is not always going to be a bad thing or even that most of the time it won't be a bad thing.
Not everyone has to think the same way you do. Not everybody thinks having a baby in different circumstances to your normal is unacceptable or even that any other lesson needs to be learned.
Unless the parent of a child is an abuser or incapable of parenting,a childs parentage is rarely going to be a welfare concern and it would be quite unusual in the absence of abuse for a different child in the families parentage to be a welfare concern. Most parents are not abusers.
