Is he ready to start baby food?

Little guys is 5 months old tomorrow, he can sit his head up on his own since 3 months old without wobble. Anytime he sees me drink or eat he wants to have what I have. Almost every bottle he tries to chew on the nipple half way through the feeding. He eats about 200mls 5x a day. My parents think he is ready, but just wondering if anyone else has had their baby chewing on the nipple and it meant that their baby was ready for solids unless it's just a thing babies do now 🤣🤷‍♀️
