First things first - the alcohol consumption. If they "have to" drink every day, then they are alcoholics, pure and simple. Which wouldn't worry me if it was just a drink or two, but, clearly, there is some heavy drinking going on, even if you're not sure that's every day.
But it doesn't matter what you (general) call it, does it? The amount of drinking you describe is unhealthy, dangerous, and inappropriate around a child. The fact that MIL, clearly, looks forward to bringing your child into this "drinking culture" someday is a huge red flag of its own, IMO. NOT saying it will happen, just don't like that this is something she's already thinking about.
Sorry, I know it's hard, but IMO, you need to bring this up w/ DH. If the word "alcoholic" upsets him, then just point out what a bad environment it creates for your child. Ask him to agree to a "No alcohol" policy (when they're there) and see if they even come (bet they won't). If he "gets defensive," so he'll get defensive, but you need to stand your ground on this - for you sanity and your child's wellbeing.
And yes, please contact AlAnon. No doubt, they can help you sort this out.
"The issue in general is that they are wanting more and more contact, seeing us for 3 days every month isn’t enough for them. "
Not enough? IMO, it's too much, given their drinking and MIL's control issues. I'm glad you're thinking about cutting back on the visits. I hope you do.
If/when they do come, despite a no-alcohol policy, IMO, you and DH will need to object every time they do something that thwarts your parenting practice. ("Sorry, we don't let LO watch TV," while turning off the tube. "No, we have a no-sweets-before dinner rule," while taking away the candy.) You may have to be the "bad guys," but you'll need to be firm. It won't be easy, but it's good practice for being firm w/ LO when you have to, LOL!
Ok, maybe you won't enact a no-alcohol rule, but one of your boundaries could be a limit on alcohol consumption. It's YOUR and DH's home, after all. And your ILs may suddenly find a reason to leave earlier than planned if they have to accept a limit.
As for the sleepovers and trips, I agree w/ others that they may never even actually invite LO for those. If they do, you can always say no. As long as they're drinking continues to be a problem (and it doesn't look as if they plan to cut down any time soon), I wouldn't leave my child alone w/ them, at all, let alone allow a sleepover or a holiday w/ them. You and DH have to protect your child. THAT is your FIRST priority.
One point in your ILs defense. ILs are often advised to communicate w/ their DS about possible activities w/ the GC, etc., and then let him present their ideas to their DIL. That MIGHT explain why they talk to DH about these things when you're not present. In that respect, they may feel they're doing the right thing. You and DH need to decide what your position is on their requests about sleepovers and holidays - even if it's just, "LO is too young now. We'll discuss it in later years." Granted, I think it should be, "There won't be any alone-time even when LO is older if you don't get help for your drinking problem," but I doubt DH will say that... sigh...
He has done it! The toolmakers son has resigned!
I hope the new PM is kind to Larry the Cat
