how long are homemade purées good for in the fridge?

3 days!

Found This.... rule of thumb is pureed homemade baby food can be stored up to 48 hours in the refrigerator. Many food safety authorities say that 72 hours is fine too. This time limit decreases the likelihood of bacteria growth in the puree. Plus, it keeps that icky “taste of the fridge” out of your tasty meals

I’m thinking of making purées and freezing them into ice cubes to thaw as and when needed
