My 10 month old is moving backwards when it comes to food. He went from eating his protein and veggie purees to eating some solids to now not really wanting either. The only things he likes are Greek yogurt (which is so confusing to me) and puffs. He's started gagging on stuff he ate regularly before like eggs, chicken fingers, even his purees. I've tried switching up the types of purees and solids but it doesn't seem to matter. I even tried tricking and mixing food with yogurt but he's on to me.
