Introducing proteins

My son has had Greek yogurt and cottage cheese and shredded cheese

I just pureed boiled lamb, beef, chicken, lentils.. and added them to his vegetable purees.

My son is 6.5mo. We just introduced meat last week. We are doing BLW: I give him long strips to chew/suck on. If you are on instagram, check out @solidstarts. My fave blw account. They also have a website and app. Shows how to cut foods into appropriate size for babies based on their age

We do blw and I did it around 8 or 9 months with my oldest, once she started getting the pincher grasp. You can also just do big pieces that they can work on. If doing regular purees, you can just puree anything you are eating, minus salt.
