AIBU to be fed up of DMs drinking?

AIBU to be upset with DM and feel like her drinking is becoming a serious problem?
For context, I’m a solo mum to a 4-year-old DD and my DM, who is in her 70s, lives with us. I work full time, pay all the bills (she buys done shopping but not all) and generally carry most of the responsibility for DD, the house, finances, organising everything etc.
DM drinks every day. Usually around 1–1.5 bottles of wine a night. This isn’t a new thing and alcoholism has already had a massive impact on our family. My dad died as a result of alcoholism and two of my brothers are recovering alcoholics, one of whom became extremely unwell because of it.
I’ve become increasingly worried about DM’s drinking, but it’s almost impossible to talk to her about it. If I mention alcohol she becomes very defensive and often confrontational, so I tend to avoid the subject.
The immediate situation is this.
For the last 10 days I’ve been absolutely hammering the house trying to get everything sorted before we go away. I’ve basically spent every day cleaning, sorting and scrubbing and several nights I’ve still been going at midnight, 1am or even 2am.
Yesterday I took DD to soft play. The plan afterwards was to go home, DM was going to dye my hair, then I needed to finish cleaning the living room, do mine and DD’s ironing and pack for our holiday.
While we were out DM called to say she’d gone to my auntie’s instead.
We arrived there at about 5.30pm and DM had been drinking wine with my auntie all afternoon.
They could tell I wasn’t myself and asked what was wrong, so I said I was absolutely exhausted and still had loads to do.
They both said, “Just leave DD here.”
I said no because they’d both been drinking.
DM immediately became defensive and started having a go at me. I actually said to her that I wasn’t being confrontational and asked her to please stop because I didn’t want an argument.
I wasn’t saying they were falling-down drunk or accusing them of being incapable human beings. I just don’t think I should leave my 4-year-old in the care of people who have been drinking all afternoon. That’s a boundary I’m not prepared to compromise on.
But there’s another part of this that upset me.
I know DM is entitled to have a life. I know DD is my responsibility and nobody owes me childcare.
But after watching me work myself into the ground for the last 10 days, staying up until stupid o’clock trying to get everything done, I suppose I’d hoped she might think, “She’s absolutely exhausted and has still got loads to do. I’ll give her a hand.”
Instead she’d spent the afternoon drinking.
And I think I just snapped emotionally. Not screaming or causing a scene — just internally felt completely done.
I feel like I have nobody I can actually rely on.
I tried explaining how I felt to my auntie afterwards and her response was basically “I’m always here for you and DD xxx”. I messaged my brother because I desperately wanted somebody else’s perspective and didn’t get a response.
So now I’m questioning myself.
Maybe I am being unreasonable. Maybe because of our family’s history with alcoholism I’m hypersensitive about alcohol. Maybe I’m expecting too much from DM and she’s perfectly entitled to spend an afternoon drinking with her sister rather than helping me.
But I’m also sick of feeling like I’m the difficult one because I have a problem with her drinking.
I don’t want to control whether DM drinks. I’ve realised I can’t do that. But I’m considering setting a firm boundary that if she’s been drinking, she isn’t responsible for DD, and that if she’s agreed to look after DD she needs to not drink beforehand.
I’m also thinking I need to stop discussing anything important with her once she’s started drinking because it invariably becomes confrontational.
AIBU?
And particularly, AIBU to say that regardless of whether DM thinks she has a problem with alcohol, her drinking has become a problem for me, and therefore I’m entitled to put boundaries around how it affects me and DD?

If your DM lives with YOU and you pay all of the bills including a large chunk of the food shop, I think you are completely fair in expecting a hand around the house and with childcare.

What is she contributing to the household? Not much by the sounds of things.

Scrubbing your house for 10 days before you go on holiday is bonkers. Relax

The shit weather will be back soon and you have the run up to Christmas to scrub the house.

My mother is an alcoholic and it honestly breaks me. She does nothing to help herself and rejects all help.

She had been ''functioning'' until about 2 years ago. She only just turned 60 and I am honestly not sure how much longer she will live.

I have had to put in some serious boundaries with her in the last year. You said you aren't trying to control your mum and that's good. But you are allowed to control what you will accept for you/ DD.

It's shite but nothing you can really do about it. Try to look after your own MH.

Also, your house is probably fine no need for a 10 day deep clean. Have a bath

Well of course she's an alcoholic and of course you can't leave your daughter with her.

Tbh I wouldn't be leaving her with her alone at any point, because you can't trust that she won't have a sneaky drink/her judgement will be impaired anyway.

I feel for you, as a single parent with an alcoholic mum also. Navigating the person you hoped she'd be and the person you're actually dealing with is hard. But your boundaries need to be solid, and probably more solid than they currently are because the situation won't get better.
