Advice for soon to be dad?

Hoping some men may be able to offer some advice. I want to help my husband. He is always so stressed out. He is literally the most giving, caring person I know, but he gives past the point of exhaustion and keeps going until there’s nothing left. There’s definitely a boundaries/people pleasing tendency but it’s also just who he is. He used to have a drink after work to take the edge off, but since we have a baby girl on the way he’s stopped doing that, but now he has nothing that seems to help him relax. I hate not knowing how to help. I have asked him directly and tried different things but even he says he doesn’t know what he needs/what may help.

What works for you as far as relaxing/coping with stress?
