My daughter hates doing this and really struggled until her molars started coming in. We still just make smaller pieces for her because she’s still just working on eating more in general. I would just find easy to bite through foods and practice & show him yourself!
We modeled what to do and then started with easy things like bread and soon after she figured it out.
Thank you ladies
Monkey see monkey do. Demonstrate it with a piece of food that you are eating
