BLW mamas

Hey there. I have been trying BLW with my 7 month old.... he'll grab the food and bring it to his mouth to bite, but then he'll kind of shudder/gag until all of it little by little comes out of his mouth. I'm not sure if he dislikes it, or he just doesn't understand the concept of chewing. Too early for BLW I guess? Anyone have a similar experience?
