DS is almost 5.5mo so this may be a silly question

The past few weeks it seems he is DYING to eat. He is completely enamored while watching us eat: wide-eyed watching and will chew along with us. He has excellent head control and excellent"hand skills," grasping any object and immediately bringing it to his mouth to chew on. by all accounts he seems ready, right?

I guess what gives me pause is when I read up on BLW, everything says to wait till 6 moths so the baby's digestive system is appropriately developed. Should I wait the next 2-3 weeks to be safe?
