Mum has new boyfriend, lost interest in kids

NC, just wanted a discussion on this. I don't want or have kids (broody hormone absent) but I find it interesting from a biological POV.

Single mum adores kid -> exciting new man appears -> maternal care hormones go poof -> kid is now annoying little pest, in the way -> neglect, abuse, abandonment, murder.

There have been countless examples of this phenomenon in the news, threads on here, and I've known a few cases in real life (my own mum was one, dumped me on other relatives so she could move away chasing men. It was much better than living with her, thankfully).

I'm curious if there's a name for it, or any research done? If not, why not? I know it's taboo to think about mothers not adoring their children, or that 'magical bond' disappearing and things turning sour. But it does happen and we need to understand how, and how to intervene effectively before harm is done.

Do you think there's any way to get the maternal love back, after the whirlwind romance has calmed/ended? That's what I find most chilling: once the hormones have faded, they never seem to return later. But I'd be interested to hear anyone's stories of mothers 'coming out the other side' and caring about their kids again.

From an evolutionary perspective, it makes sense that a new man wouldn’t want to raise someone else’s kids, therefore has some sort of influence on the mothers and in turn the mother wants to procreate with a man who is going to stick around and help her raise his children.

Oxytocin is also involved in romance, is it not? I'm curious how the focus gets shifted from kids to new man, as if he's replaced them as mum's top priority, and they're forgotten.

It doesn't always (or often?) happen; some mums fall in love with new partners but it doesn't affect the maternal bond. Wonder what the hidden variables are, in the brain.

Children often aren’t mums top priority though, many mums struggle to bond with their baby and many find parenthood an absolute drudgery. I don’t think hormones play as big a role as we imagine nor do I think a maternal bond or instinct comes naturally to many people. Mums tend to be primary carers because their socialised to be, and I guess their attention can be pulled in exactly the same way as a man.

Equally people can bond with and have deep love for children they have no biological (hormonal) link to.

I was reading something about two little boys abandoned by their mother and her boyfriend and someone commented that the biggest factor in child abuse or murder is if the mother gets a new boyfriend. I don't know if that's true but if it is then you're definitely right that it should be studied to see how this happens, how it can be predicted, support, changes etc.

I think women who do this have personality disorders and are narcissistic people.

No mother who genuinely loved her children would dream of doing this.

Many men do it with ease.
Even men that "love" their children, happily put themselves first.
Its just who they are.

Not all men, sure. But a lot of them.
Even men who consider themselves good fathers, just somehow put their comfort and themselves, first.

"No mother who genuinely loved her children would dream of doing this"

That's the thing that puzzles me about these cases. Because as far as anyone can tell, the mums do absolutely adore their kids beforehand. Deeply attentive, would die for them, do anything, born to be a mother, yadda yadda.

But then it... disappears. And in some cases I've heard about, it can be very quick, over a weekend even. Suddenly the kids are just pests, mum doesn't want to be around them, snappy and impatient and rough, no care at all. The new romance has bewitched her.

It's a frighteningly dramatic change. I'm not sure 'personality disorder' really fits. More like a mood swing? But I've never heard of it swinging back afterwards...

It's not down to hormones - if you're the type that prefers to be in a partnership to face society, bill paying and life, then you'll probably be successful in that endeavour. Moreso given the LTB mentality as a cure all that aids the pool of available men also needing to form a new partnership too. The increase in blended families does evidence this a bit.

I'm not of such a 'needy' personality myself but I do believe that most of these newer/2nd partnerships don't result in CSA/child neglect, etc.

Problematic in other ways, often yes, but not usually to extremes.

I think you're right in that it's rare. Plenty of mothers are capable of getting new partners without losing interest in kids. Those extreme cases are what I'm wondering about. The change happens so rapidly and completely - the kids were utterly adored last week, now mum wants them out of her sight and has zero time for them - what could that possibly be, if not some kind of hormonal shift?

Reducing motherhood to hormones is reductive and misses vast swathes of socialisation, trauma, lots of things that affect relationships.

My take? If women weren’t trained from birth to centre men’s needs and feel like they are failures without one, and society wasn’t set up to be hard for single women in particular, you’d reduce this issue by more than half immediately. Hormones or no.

Edited

Hormones are just one aspect, that I find interesting in a logical flowchart sort of way. (I'm autistic and curious how brains work, I don't mean to offend anyone)

But you're absolutely correct about the other things counting too. My mum was deeply ashamed of being a teenage single mum, envious of her friends getting new partners/married etc, and desperate to 'redeem herself' by finding a respectable man, house, picket fence, 2.4 new kids with him. I was an embarrassment, a hindrance, damaging her reputation and image (especially as I was developmentally delayed). Things might've been different with more support, less pressure on her.

Ive seen it loads to. New man, lots of baby sitting requests. Ignore kids while on phone the whole time. Buy new outfits when they cant afford new shoes for kids.
Someone even asked to babysit for two weeks while they went on holiday (she'd known him for a month)

3 that i know all had not the best upbringing.

I did it somewhat too will admit that. But more like can you watch kids for an hour for a coffee date after a few coffee dates id sneak out in an evening while babysitter was downstairs and kids asleep (still feel guilty for it)

There were two somewhat neglected children at my primary school - they smelt, basically, although they did turn up at school so Mum clearly had some idea. I remember seeing the Mum
at some kind of school picnic and she was canoodling with a boyfriend. This was really not what the mums we knew did - they stayed at home and cooked for our dads. Happily we’ve moved on from that limited set of possibilities for women but I feel so sorry for those kids - everyone was mean to them at school because they stank and had no manners and Mum just ignored them to snog her boyfriend. I think he was horrid to them as well.
So sad.

You're probably thinking of oxytocin - triggers contractions and lactation, and is called the 'cuddle' hormone because it supports emotional bonding particularly during skin-to-skin contact. But it isn't exclusive to women, although they produce more when pregnant and breastfeeding.

Oxytocin is also involved in romance, is it not? I'm curious how the focus gets shifted from kids to new man, as if he's replaced them as mum's top priority, and they're forgotten.

Being a single mum means you get judged so much. I've had a tough time throughout my life but have never been so disrespected as when people find out i'm a single mum

For some women, their life changes when they get married and theyre seen as more respectable

Then when the inevitable issues of forcing some man to be your kids dad arise, the woman decides her kid is to blame for being naughty

Kids dont need a father figure more than they need a sane and strong mum, who fucking wants them

We're too far advanced in society to not see the damage bringing a man into your home is doing to your kids. Just be a single mum and embrace your kids!

I don't lnow how much is hormonal and how much is therapy - often these women didn't have happy upbringings, they're following a toxic pattern they can't break and need male attention to feel worthy, in need of therapy - its like how some women can't just be happy and single without always needing some man

Oh, and before anyone says "why focus on mothers? what about dads who abandon kids" - yes I know loads do, they're shits.

But the powerful maternal care hormone (whatever it is in humans; prolactin is the one that makes birds care for chicks) is exclusive to mothers, I think. Giving birth sometimes triggers it immediately; other times it appears later after 'going through the motions' and caring for a baby for weeks/months.

I'm not trying to judge struggling single mothers here, I'm just interested in that hormone's disappearance and how we can deal with the resulting issues. Like a scientist.
