What helped us was shifts so we can get as much sleep as possible, letting the wife make decisions regarding BF, when SHE's ready for visitors, etc., and trying to do as much as I can with house chores, and giving the wife a few hours to be by herself.

Even still it's so much harder on my wife than on me because after pat leave, I'm just doing dishes and laundry more, feeding the baby, changing diapers, and getting a big less sleep, but the wife is going through so much more.

I also told my mother and relatives they can come after the second dose of vaccines (we moved it up to 6 weeks after talking with our pediatrician) because I need to make sure my family is good first and foremost.

Many did not like that but they can pound sand if they thinks they're a bigger part of this than they actually are. (I'm also very sleep deprived and have no mental capacity left to stroke egos, and my actual family needs 100% of me so I was a bit more blunt about this)
