My wife is not BF so it will be formula only so we are trying to prep registry if we need bottle warmer or sterilizer which I already removed.
Neither of those items are necessary, nor, IMO practical. I skipped them, never missed them and I'm all about convenience.
Are you certain you'll use formula? Have you ruled out breast feeding? I'm not trying to start a debate but you don't want to load up on formula, obviously. Also, if you do go with formula, your baby may not tolerate some so again, don't load up!
