Hi All, Iv started giving my little man finger...

Hi All, Iv started giving my little man finger food, so far he has had fruit, 1 hot chip (naughty mummy), cheese & some arrowroot. I want to start giving him toast, bread & other things but im really scared he will choke.. Any tips on trying to prevent choking? Any other finger food ideas would be great to as im slowly running out of ideas.. Many Thanks Alicia
