As babies, my (6) brothers and sisters and myself were fed homemade baby food. It was either my grandmother or my mother’s creations.
I do not remember seeing jars or if I did they were my grandmother’s homemade preserves.
Most of us now do not take (or have) the time to cook our own baby food. Out of guilt or/and concern for kids health, new parents are now focusing on healthy and nutritious alternatives. 
Companies such as Bohemian Baby offer Organic choices.
They offer Home Delivery in Los Angeles and parts of Orange County on Tuesdays and Fridays only and Ship anywhere in the US.
Note that a Jar of Bohemian Baby Food will set you back $2.50, upscale we go.
I first heard about Bohemian Baby while listening to Marketplace morning report.
