Leo does this a bit too, sucks and chews on the meat for quite a while. I gather he is enjoying the taste, but meats, even mini meatballs, seem to take a long time for him to eat.
I started Leo on what I call toasted sandwiches. I simmered a steak in water, pureed it and added some other things like pureed sweet potato and cheese.
Then I added to a sandwich and flattened them a lot while toasting in the frypan (flattening them really well helps stop all the meat falling out when he eats them). I cut them up into small squares. He eats them frozen, chews them down like a teething rusk!
Roast chicken from the supermarket goes well.
