My daughter BARELY has 1 tooth, and we have given her TINY TINY pieces of steak, chicken, and turkey. Your son doesn't need teeth, his gums are hard enough where his molars will be one day where it will chew the food. Just cut the meat up in tiny pieces. Avoid any extra salts, or added things like garlic on your meat, or anything like that. Introduce it slowly. My daughter is 8 months old.
