Mine are 10 months old.
strips of - grilled cheese, toast with cream cheese, toast with eggyolk and sour cream, pork strips, beef strips, strips of burgers (made without eggs), brisket, watermelon, cheese, cucumber, the chewy or brittle stuff I tend to cut in small strips.
small foods - cheerios, ritz crackers broken in half, macaroni and cheese, chilli-mac, the shredded chicken on the inside of enchiladas,
whole peaches, pears, nectarines and plums -watch for seeds on the plums. I also love the whole skinny green beans (varicot) and asparagus -although that can be tough sometimes.
chunks of avocado, kiwi, beets (they love beets), sweet potato, curried potato, blueberries cut in 4 or 8, peeled grapes cut in 4-they love broccoli and cauliflower crowns -just like I'd eat - just about anything goes -they will surprise you. Seriously.
Couscous and a white sauce is good - I can make those into little cheese balls. I also boil potato chunks and then peel and toss it in olive oil, garlic powder and parmesean and bake it -they LOVE those. Baked sweet potato is a good starting place too.
I try to watch the salt and sugar because as adults we eat way too much of that stuff.
It's very scary - but know there is a difference between gagging (which they will do) and coughing (also something they need to learn to do), and choking. I had one time where we had to grab my son out of his high chair - he was coughing hard, but he was fine - we just panicked.
They can also feed themselves -load up the spoon with something a bit sticky (not too sticky to be a choking hazzard) -oatmeal, lentils, rice and something to help hold it together (e.g. eggplant or bok choy -might need to whirr that in the blender) etc and they will be able to get the spoon into their mouth remarkably well. Will it be perfect -no -but they'll get the hang of it really quickly.
