Choking hazard?

KaylaO1024

So my son is starting to want to feed himself, and I'm never sure what is safe to give him.  He's had mashed potatos and noodles (plus puffs of course), some cherrios and bread, but anything else I'm nervous.  He has 6 teeth now, (2 more are on their way in but not cut yet).  What do you give your baby, and has any of your children choked on food?  What do you do if they have choked?
