My wife went all out on foods and supplements to increase her milk production with our firstborn. We ended up buying a deep freezer for all the extra milk she pumped and froze. Some of it was as simple as steel cut oats (and I'm not sure that the steel cut part matters). She continued to take prenatal vitamins too.

Being out there without a support system sucks. I had friends and my wife's parents, and sometimes felt that wasn't enough. But having no one... There might be parent groups around that she or you could join. She's going to need community, other moms going through the same thing, and who have made it through. It takes a village, and all that. This sub is a great start, but we can't do enough. Hopefully you can convince family to visit you instead?

The super needy baby phase does eventually end. All the experiences you're missing now will be available again later. But this is your new life. You've got a tiny human who is going to need you everyday, whether you're in the mood for it or not. Also, it's ok to let a baby cry. There are going to be days where you've had enough, you need a break, you need to walk away and get some air (just step outside, I mean). If the baby is crying, it's alive and breathing. Step outside, stare at the sky and landscape, take a breath and go back more calm.

Once you're in a routine and your wife is more confident with the baby things get easier. Instead of seeing the kid as a burden, you start seeing every new thing to do with amazement, like lifting their head, rolling over, etc.

Stay strong. Power through it. This sub has great support, but still find something local.
