To report next door neighbour for various issues?

[peanutcoco]

I was quite close with my neighbour who lives opposite in the cul de sac where I live.

We just immediately hit it off and would talk for ages and go for drinks at each others houses.
This was always instigated by her as she didn't have much of a support system other than her parents.

I always thought she was a sweet and genuine person up until recently.

It's like she has had a personality transplant.

She swears about other neighbours behind their backs, very sort tempered with her toddler, and basically has this arrogance about her since she began a new relationship.

She has started having issues with alcohol and they both get drunk together after the child has gone to sleep which could be part of her personality change.

She confided me in when he first moved in (been together 3 months) that he is 12 years older at 40 and she pays for everything.

He moved out of his parents into her house.

He pays nothing towards anything as he is just establishing his self employed business.

Its all very strange as she dosent even trust him with a house key, when she leaves for work and he is asleep - the door will be left open after he has left for work and she would ask me "to keep an eye out" despite having a ring door bell on her front door.
I find this quite risky and very strange.

The other night I saw them come back home in their own separate cars with the child.

When the child was asleep they both went to the shop to buy alcohol and the child was left alone sleeping for around 10 minutes.

I just can't help feel sorry for the child as he has taken a back seat.

They also play loud music, God knows how the poor kid manages to sleep.

All I did was politely text her asking her if she could turn the music down and she has blanked me since.
Walked straight past me yesterday.

There is a small alley that allows access to our properties and a third house and she uses this to store her bins so they don't take up space in the garden.
Surely this is a hazard?

She muttered "bitch" when her and her man saw me today with my kids.

I want to report her for all these issues (music, blocking communal areas and safe guarding) but I'm thinking maybe I am being too harsh?

AIBU

You have to report on the basis that a small child was left alone.

Yeah, leaving a child unattended I’d probably report that. I didn’t see how old they were but she sounds like a very irresponsible parent! Or maybe you could say to her ‘I notice you left X at home… you can always message me jf you’d like me to watch them while you pop out’ to see if she realises what she’s done is a safeguarding issue

The child is 2.
Who would I report it to?

MASH team at your local council

Safeguarding is everyone’s responsibility. It could be that another neighbour has seen this too. There is no guarantee that this very young child won’t wake up at night and anything could happen.
You are not being too harsh but it must be stressful thinking of possible consequences if you report.

Yes I think if I report her she will defo know it was me and I do worry about the consequences.

She is a deeply unpleasant person, even yesterday she was going me menacing looks when she was with her boyfriend.

Child left alone isn't ok. I would report that to social service.
The rest isn't any of your business.

I’d speak to social services about the child being left alone, but the other stuff-who would you “report” it to? It’s just a sad fact of life that some people are assholes, and it sounds like that’s what your neighbour is.

The issues relating to the child are a different level of seriousness so focus on that first - contact NSPCC for advice if uncertain.

For the other issues - what is the housing situation of both of you - owned, private rental or social housing? You have different options in each situation. But these are not urgent, just annoying.
