Staining hasn't really been an issue with us. Maybe a handful of shirts have small tomato sauce stains, but it hasnt' really been a problem. Babies/toddlers wear fabric bibs for the major stuff. I usually rinse or shake off food chunks before throwing in the hamper, or will soak everything before putting straight in the wash if it's really messy.

We use small washcloths for everything: https://smile.amazon.com/Spasilk-Pack-Soft-Terry-Washcloth/dp/B002LARFQ4?ref_=ast_sto_dp&th=1&psc=1 I love them!

We have very old wood floors with wide gaps between planks, so we put a vinyl floor mat under our kitchen table to help with overall cleanup. It looks nice (not "kid" patterned) but is a breeze to wipe up.

Other than than? nothing so special. We tried those suction bowls but they didn't work well. Rice is a pain to clean up but so be it. Yogurt etc just gets wiped up. It's a lot of clean up, but nothing to overthink. And self-feeding and playing with food is all part of the process, so just try not to stress!

When you guys say the clothes are ruined, why? I mean food stains are not impossible.

We strip down to the diaper. Extreme, but otherwise we'd ruin all his clothes. (And breakfast and dinner are interludes between clothes and PJs, then.)

We always did bath right after dinner and reserved the messiest foods (yogurt, marinara sauce, etc) for the evening meal.

We didn’t do full baby led weaning, but started with pre-loaded spoons from day one. The key is to have three spoons so that you can keep trading an empty spoon for a loaded one.
