Because you're still working, you get 8-9 hours a day off from being responsible for the immediate care of the baby. Your wife probably feels like she gets zero hours off. Is she eager to get back to work or just to get out of the house and get a few hours off? Could you work from home a few days a week or drop down to 30 hours a week so she could have some time to feel like a professional more than a mom? You're both really stressed and your lives have changed a lot, but hers has changed more than yours, at least for now. Can you leave the baby with her grandparents and go away for a weekend?

I agree that a bit of formula is going to be fine for the baby. The more important thing is a happy, loving set of parents who aren't resentful of the awesome thing they made. If the crying and not sleeping doesn't stop soon, it could be attributable to an allergy or food sensitivity. Your wife can either go on a super bland and shitty elimination diet, or you could talk to your doctor and see if formula exists for super allergic kids and just try him on that for a few weeks and see if it gets better. Food allergies are really common nowadays, and it's an easy thing to fix.
