Each weekend I would shop the market to buy fresh in-season produce such as sweet potatoes, carrots, cauliflower, green beans, etc.
I then steam them up and freeze them in zip bags to use throughout week.
Take out ,thaw in refridge, blender whip for small child or spoon reheated for 6 months and older.
Same with meats. Boil and freeze then mash or cut very small.
No need to buy jars of expensive baby food.
