For ones you buy at the store it says use within 24 hours of using I would stretch that to a couple days especially making it at home. But if it hasn’t been touched and just made I might do a week
i leave for 3 days. i guess it depend if you use breastmilk then 4 days max
Freezing it would last more long term I’d try packaging it per serving so you can just take out what you need from the freezer, and you could leave like 3-4 unfrozen to start with if you think you’d bus through it in like a few days to a week
I don't go longer than 3 days. If you're adding milk, do it when you're ready to serve. Not the entire container
I’d probably leave it for 5-7 days. I’d look to see if it smelled weird or looked weird. But I think I’d mostly do a max 5 days
