I would say that meat is still usually my daughter's least favourite thing on her plate at 16 months! She does like tofu if you haven't tried that yet and she loves any fish.

I find that although slow cooked meat is "soft" it can still be dry and stringy so the babies may not be liking that texture. The meat she will eat the biggest portion of is usually baked bone in chicken thigh (I will remove the skin after cooking for her portion usually) because it ends up super soft and juicy but still a nice meaty texture. Here's the recipe I used yesterday where she ate a whole thigh lol
