why my baby refused real-food---- always????

My baby seems perfectly content with their milk, but the moment I try to introduce real food, it's like I'm offering them the moon on a stick (and not in a good way) Is this normal? Am I doing something wrong? Here's what I've tried so far: - scheduled feeding - eating on high chair - exciting menus - sensory play (idk how it's related but everyone told me to stimulate her sensory more often) Nothing seems to tempt those tiny taste buds! Any tips or tricks for getting my baby on board with the exciting world of real food? Bonus points if you know: How long is it typical for this "solids aversion" to last? Are there any signs I should worry about (beyond the epic food fights)? Thank you very much
