@Wolfcubisthefemalenominal and @ListeningQuietly thanks for ideas, but unfortunately DS has huge sensory issues :(
We tried frozen strawberries in March, but they were too "wet", and he won't drink smoothies because of the bits.
I have got my NT DS eating tinned fruit, so I'm going to stock up on that for him, but I'm a bit stuck for ASD DS and DD.
So far, on my list I have raisins to replace grapes, frozen sweetcorn (with a few tins for backup), orange juice ice lollies, baked beans and spaghetti hoops. I've also bought some gummy type vitamins.
Does jam count? I usually buy the smooth bitless jam, but DM would happily make some for me, but how difficult would it be to get the bits out?
I have a book reserved at the library called 10 a day, I"m hoping it will give me some other ideas.
