What happens if you chop up his usual foods to be eaten on a spoon??
I am going through a similar thing (look on my thread if you want). Last night I tried mash sw pot and chopped beef and he refused it. Chopped up his usual finger foods of chicken and avacado and he would happily eat from the spoon

This is a quote from my thread from Kathryn that has worked for us already tonight!
"I wonder if it's related to the food itself, rather than the fact that it's "finger food", so for example, has he learnt that 'when mummy gives me a bowl of stuff I can't see what's in the bowl, and it's possibly going to be new foods, so I am going to refuse it without even looking to see what it is, waaaah, but then the stuff I get on my tray to feed myself "tends" to be familiar so I am comfortable with that and if mummy sneaks in something different, eg sw pot chips, I am ok because I can see it and poke it before I decide whether I am going to try it' Does that make sense?
If so, I wonder whether you should give up with a bowl, and start to use a plate for all meals (apart from breakfast, obvs), so he can *see* everything, and have a mixture of finger and non- finger foods, and give him a spoon, or might be better with a fork, and have at least one new thing on his plate with a few familiar things each time, but the point is he can see everything so will become more comfortable with the idea of crockery & cutlery, kwim? And hopefully become more comfortable with new foods being offered too."
I made mince meat in gravy and mixed it with food I know he loves - peas, sweetcorn and pasta and then put it in a large, flattish bowl (or even a plate with a rim) so he could see it was foods he liked. He ate the lot! Some I fed from the spoon, some he ate with the spoon some he picked up - pretty great I think!
