Hi! Some of the Tesco baby food pouches I have say to use immediately once opened. Others I've tried before say fine to store in fridge for 48 hours after. Is this over cautious guidance or does anyone else use next day? It just seems a waste when she's only eating small amounts from them just now (and her lips arent touching the pouch). Obviously I don't want to give her a bad tummy so if they need to go in the bin after then fine but just wanted to see what others do!
