The moms used to chew up mangos, oranges, blueberries, bananas, fruit etc and then spit it into the baby’s mouth. Thats how monkeys like orangutans do it. Back in the day if you didn’t have a wet nurse or your wife died or left or something single dad’s would do this like the pioneers. Most babys can eat soft stuff at like 4-6 months if they really want to .
