Baby food is as expensive as finely chopped or mashed vegetables. It does not take long to mash carrots or potatoes. Even making meat paste is trivial with a blender. Diapers really are expensive but baby food should not be breaking the bank because they just don’t eat much. Unsalted mashed up vegetables and small portions of fish, egg or meat aren’t really expensive.

Baby food makes no sense. Chew your own food and put it in baby's mouth, just like humans did for the past 100k+ years.

Good for microbiome, too. Lazy parenting is (usually) good parenting.

I would advise against that for anyone with oral herpes (cold sores) even if you’re not presenting. Also there’s a limited amount of food baby can eat when small. Don’t chew pizza and give that to a three month old.
