I prepared 60ml of mix vegetable and fruit puree. I placed it in a air tight container. Then i put in e fridge not freezer. Upon feeding i took out the container to thawn uding hot water in a bowl. After that 30ml balanced puree i put back in e fridge. Am i doing the right thing.

i wont refrigerate for more then 24 hours. once i take out I'll use and throw the rest. if you want to keep it longer then freeze them into your daily portions.

Yes you can. but after thawing, keep for another 24hrs max. But do taste test first before serving

I did that too. But usually I will taste it first before serving to the LO

Refrigerate for max 24 hours - otherwise dump it pls
