Question for all parents

What do you ACTUALLY need to have a baby?
Like even babies/children have been pulled into the consumerist ideals.

How essentail are high-chairs? Tummy-time pads? Baby bouncers, sleep sacks, baby baths, grooming kits, playpens...

How much of it is a parenting NEED vs just comsumerism trash that overtakes the home 🤣
