Should I report this mum? Is it even reportable?

You think no child was ever abused by their traditional married parents in the past?

Concerns based on what? She's a mum and also has a boyfriend? How very dare she !

She now has a new boyfriend already. She's posting him on social media and making comments that shows he's staying (living?) round hers with the kids. She keeps basically moving strangers into her home and allowing them to play dad.

That wouldn't be considered abuse or neglect and it's not a matter for social services.

I completely understand why you're worried, but having someone to stay at your house - or move in - is something everyone is perfectly entitled to do, kids or no kids. People are allowed to have boyfriends, lodgers, friends, housemates or family members living with them and that in itself wouldn't warrant social services getting involved.

If you have a genuine reason / evidence to believe that her boyfriend actually IS a danger to children (rather than just imagining that he might be on the grounds that he's a stranger to you) that's different and absolutely social services would want to know if someone who was a convicted paedophile or domestic abuser was living with a child. But it doesn't sound like that's the case.

If you think the children aren't being fed, kept clean and cared for, then of course you should absolutely report that.

The children have a right to be safe.
Feel sorry for little ones today. They get no choice in who their mum moves in.
Society's gone down.

So what’s the answer, only middle class married women can have a baby?

Absolutely report her to the future crimes division...

Getting pregnant is not a crime. Everyone has the right to make an unwise decision. So unless you suspect she lacks capacity, there is nothing to report.

Blimey.. it must be nice that your life worked out so perfectly but that doesn't happen for everyone. As pp said, unless there are concerns the children are being harmed there is nothing to report!

You can’t report someone because you don’t agree with their relationship choices, even if they are seriously questionable . Unless you have some evidence the children are being neglected or harmed what would you say and expect to happen? They won’t accept the argument it’s common sense they’ll get mental harmed, you have no proof of that.

Possibly a side-issue in terms of immediate needs etc, but we all know this is not good for the kids' mental and emotional health in the long run, but there's not much we can do except be bystanders to a slow-motion car crash. Such a pity.

I know someone that did this with 6 children, they’re grown up now and wonderful adults that love their Mum, you can’t police someone’s bad choice in men unless they are actually doing harm to the children. I know far more fucked up adults whose parents stayed together unfortunately.

She's concerned for the kids safety. As their shitty mother keeps moving strangers into their home.

Alone, it meets no threshold. Nothing would happen. That said - there may be things you don’t know. Things previously reported by neighbours, something the nursery spotted on the toddler, etc.

Safeguarding is about building a picture - this is your jigsaw piece. Report, but don’t expect an outcome as such.

You sound very judgmental.

It's not an ideal way to live but unless you suspect these men are actually dangerous or harming them, then what are you reporting? Social services and/or the police don't have time to investigate every single parent who is dating.

Has anyone got enough detail to do a Sarah's law request? I would consider that if you had specific concerns around the new boyfriend.

For what?

It sounds like you're concerned that even when this woman knows a man has a criminal record, she still moves him into her home, so maybe this current one could be the same? I'm not sure how it works but maybe social services can check whether he has any relevant restrictions. I can understand your concern, especially with childhood young to advocate for themselves or reliably report anything untoward.

How do you feel about you partner's attitude to all this? He's not coming out of this well either.

Report what exactly and to whom? Just because it's someone you wouldn't go out with, it doesn't mean he's done anything wrong.

Based on the facts you have given, it doesn't seem like she keeps moving strangers in, but rather she has had two relationships with a child being born during each and now she has a new boyfriend. Have you even met him?

I'd probably report it to social services so they have the information available as part of a larger picture if they have other reasons to get involved with the kids. But in itself, as much as it's really damaging and dangerous for the children, it's not illegal and not a recognised form of abuse.

I can see why you have concerns about the impact of the mums choices on the kids and I don’t disagree. But unless there is actual evidence of something happening, there really isn’t anything anyone can do. Threshold for safeguarding is very high. This is not likely to trigger any action.

The OP did ask if it's "even reportable".
