How do you tell when it is ok to give you LO baby food puffs?

Amber

My son is 8 months and LOVES food. He has a great appetite will eat any flavor of stage 2 that we give him and is always watching us when we eat. Now that he has the hang of putting things in his mouth I wanted to try the Gerber Graduates Puffs but i don't know how to tell when he is ready for something like that. When did you all start giving things like that to you LOs?
