If it’s your first, I think you won’t be able to prioritize each other. Hormones or not, brains stop working. Communication becomes sparse from your husband and not for his lack of trying.
We have my in-laws living 30 mins out who think we should be able to handle the baby ourselves in my week off( I work week on, week off schedule). Feels like a full time job in my week off with my wife expecting me to do more as I’m home. Can’t explain to them why it’s not as simple as that especially when I can’t get anything done in my week on due to 1 hour commute and 12 hr shifts.
Your situation is different but I’m sure there’ll be things that’ll come by. Be sure to hire help at least for 2 months or so.
