How long did you feed your kids purees? When did they start eating only table food? I'm trying to figure out how many puree cubes to make.

As background, we are BLW failures. LO would get so hungry he would stuff all if his food in his mouth and choke. We also are dealing with multiple food allergies, so common "first solids" 7are out. . LO is 7 months and is breastfed. He eats solids 3 times a day-- between 10-12oz
