I am going by your username here and if you are indeed in Dublin or Eire I would give these people a call.
You need to remember the 3c's when it comes to alcoholism:-
You did not cause it
You cannot control it
You cannot cure it
At least you are no longer drinking with him (a Big NO-NO in any event); that was enabling behaviour on your part which actually helps neither of you.
You cannot enable him, many people in these situations end up as their partner's enabler. I presume very few people in your real life know about his drink problem and that you have made many excuses for him and or his behaviour in the past.
You also have to prepare yourself that he may not listen at all to your words re his drinking. Or he'll cry and make all sorts of promises, promises that will not be kept. Denial also is present in these situations and your H likely underestimates how much he is actually consuming.
Unless he comes to realise that he has a drink problem and wants to tackle it there is nothing you can do to help him. All you can do is help your own self (this is where Al-anon comes in). You are ultimately only responsible for your own self and your baby, not him.
Growing up in a house where one parent is alcoholic is no fun for the child let alone the spouse and can actually give the child a whole host of problems. Your baby and you therefore need to come first.
