Does my husband drink too much?

My husband and I have a baby that is 3 months old. Since becoming pregnant and giving birth, I noticed that my husband has started drinking more. He goes through one 750 ml bottle of Whisky per week as well as a couple of beers (1-3 per night). He even drinks alcohol in our cupboard which he has mentioned is “disgusting” (stuff that has been gifted to us).

Is he drinking too much or am I overreacting here? I’m honestly worried that his drinking has worsened and that it will impact our family…he has also come home wasted a few times (one a month) and I don’t trust him wasted around our baby…

I’ve asked him about it but he has denied it…and just says he has one beer per night with dinner (which I know isn’t true…). I typically go to bed about an hour after I put my baby to sleep…my husband goes to bed 1-2 hours after me which is when he does his drinking…

*I grew up in a household where my parents rarely drank…maybe ONE beer at dinner at most.
