DD will only have a few spoonfuls as I am just introducing her leaving me with almost a full jar or pouch which I then put in the fridge. Is it right to put them in the fridge? How long until they go off?
Most are 24-48hrs I would suggest batch cooking some sweet potato, carrots etc etc and freeze in ice cubes then mix and match flavours as her appetite increases and then freeze mashed up baby size portions of family meals and keep pouches and jars for if out and about or in a rush as they are expensive and in early days as you are finding wasteful.
Although 3weeks in my 24weeks old can polish off 3/4 pouch or 1/2 pot fruit.
