Anyone else having the worst time with baby food??

My son is seven months old and still not eating baby food. Any attempt at giving him baby food just ends up with him slapping the spoon out of my hand and slinging food everywhere. After two or there times of him slapping it out of my hand I’m too frustrated to do it anymore. He’s never interested in the food. If he’s not hungry he obviously won’t eat it, if he’s hungry he wants milk and still had nothing to do with baby food. We’ve tried every flavor and tries cereal. I want to just stop trying to give it to him but My husband thinks we should keep giving it too him but I feel like there’s no point when he’s literally eating none of it and we’re just wasting it
