I wouldn't give Ritz crackers, or at least not a lot. Nutritional foods are better right now.
Sweet potatoes in chunk sizes they can pick up, they much right inside their mouths.
salmon (great for iron)
egg yolks (also great for iron, some wait til a year, but 11 months seems close enough to me!)
Ripe pear (peel half of it, and let him gnaw on it, whatever pieces he gets will be soft)
Rice (brown rice works too)
carrots cooked very well, soft
ground beef, small bits
pot roast (beef, potato, carrots, green beans)
broccoli soft (let him hold it and eat the top)
