This is true. But my ds is fed formula via a feeding tube. He has a lot of food allergies requiring he be on a special hypoallergenic formula. He eats some regular food but not enough to sustain himself. He gets 100% of his needed nutrition from formula and any foods he eats is just bonus calories/nutrients for him. He's on his feeding tube 24hrs a day. I'm a mom grateful for formula. It's what keeps my son alive.
