Boy, are you with the program.

Think through every purchase. Make sure you really need it. Also, own objects that will last, ideally made by artisans.

Are you growing food too?

Have your kids read the classic books of western civilization. Teach them true and patriotic American history. Easy to find a list online.

That is awesome you have the support; super necessary especially with your first as you guys will be wiped out. Remember if you are struggling, don't suck it up let people know, post-partum is real (home birth great, you will avoid them pressuring you with pitocin/vaccines, not that you give in to anyways).

I would say you likely don't need a diaper bin (most of time you'll just be tired and throw in a trash can). Assuming your wife will pump; breast milk bags a must but you really don't need to go crazy on the cleaning. We rinse everything under warm water and good to go, some people go to ridiculous lengths to sterilize etc...remember your body is amazing and will be good to go.

Remember, you won't need a million outfits during the newborn phase, lots of times you are going to be so tired you will put in whatever is close and clean. Constant stock of diapers and wipes is a must, mobiles, toys etc truthfully you don't need to much of b/c baby will be focused on you guys during newborn phase. Don't go crazy with a baby tub, just something simple that you can wash your baby in, remember you will be holding them at all times so features/style don't matter. Have thermometer on hand in case baby gets sick, first aid stuff, silver metal nipple covers for your wife's breasts as will get sore and cream for her and baby.
We rarely used our basonet...baby slept next to wife for most part (they say this is frowned upon so whatever you are comfortable with) just make sure no pets in the room. I would have crib or basonet, but again if baby is sleeping in bed basonet rarely used and had crib in separate room if needed privacy. That's why I say maybe don't need basonet but your call. Have one decent stroller, getting out and walking so important. Just make sure its versitle, nothing crazy; I doubt she will be running so you don't need to go to fancy and will take her body a long time to recover so walking should be fine.
With closing functionality is key....avoid excessive buttons snaps. Onesees are very easy, remember as much as you think you will be out and about often you likely won't be. Patience is key...use each other; make sure each is getting rest. Find a routine that works and stick with it.
Biggest waste is likely the camera; although as first time parents you may still want it. We found with our first we were checking camera constantly when baby was napping in crib....with 2nd we had faith. It's hard, your call, but likely you could pass on a camera. Hope that helps! Any other questions feel free to ask, wife do any day, such a blessing to bring another child into the world!
