Baby Led Weaning

Hey all! My babe will be 9 months old on Friday and we have been trying BLW for a while now. She refuses purees and has been getting better with trying new solids until recently. It's like she's forgotten she needs to chew her food so she's trying to swallow things whole again, causing gagging until she's throwing up what's already in her belly. Is there any possible way to reinforce chewing? Would it be counter productive to try purees again?

Apples are her favorite and she tends to just suck the juices out 😂
