Things people say you need to worry about that you don't actually need to worry about:
Bassinet / sleeping through the night - myth
Nursery / crib - did not need
Nipple confusion - not a thing
Freezer stash - high lipase
Breast pads - I don't leak
Pee pee tee pee - it happens fast, the golden fountain, as we called it.
Bibs - the puree phase was the only time we bibbed. Lasted about 2 months. To be fair our baby wasn't very drooly and he hates messes.
Sleep sack / swaddle - still do not understand this. My kid has always needed his autonomy of all limbs.
Walker - hated it
Protect your milk supply / Build up a freezer stash
You can change your baby anywhere (couch, floor, grass), you don't need a dedicated changing table - Myth
