If you buy a used crib just make sure it's in good shape and hasn't been recalled.
More practical advice: Costco brand diapers and formula are the cheapest we found, but still good quality. Well worth the membership. There are also ways around going to Costco without paying for a membership. You can just google it.
Walmart brand wipes were the cheapest (and not useless) ones we found. We buy them in lots of 1200 at a time for about $20.
I saw that it was a perfect fit so I bought 10 more.
And then I had to return them because my wife wanted variety...
My way of rationalising it is whether she'd rather have us spend all we could on having the best of baby gear now, or whether she'd rather have it in a savings account when she is looking to buy her first house, go to university etc.
Dude - relax! Becoming a parent is a real emotional roller-coaster, and it's hard to keep your perspective, especially with your first, but remember - all kinds of morons have kids, and they're fine. Perfect is the enemy of good in this part of your life too
(my kids, and all my friends' and family's kids, wear and have worn hand-me-downs almost exclusively, except for fancy or special-occasion clothes)
So, so true.
Some parents feel guilt about buying used things for their child, and end up spending a lot of $$ on new clothes, crib, etc. for a child that will not benefit from all that extra expense in the least. You don't want to cut corners on, for example, health care or quality food, but things like clothes because they are visible can cause some parents of newborns to spend a lot of money they don't need to. Save it for the things that actually matter.
