Red meat is a difficult food to digest, partly because it is chewy so is still quite solid when you swallow it, and partly because of the protein and fat in it which take more digesting than carbs.
Some people eat baby food because it's cooked and mashed. Sometimes in a flare, particularly if you have strictures, cooking and mashing veg breaks it up and makes it easier to digest. Baby food is also likely to be bland and not have spices or other stuff that could upset your stomach.
As for coffee, some people have to cut it out, others don't. I find I can have coffee with a meal, but need to be careful how much I drink on an empty stomach. I assume the food absorbs the coffee and prevents there being a 'tidal wave' of caffeine scouring the gut walls (if that makes sense!). You could try cutting it out to see if your symptoms improve, or keep a diary and see if there is a pattern between drinking coffee and your symptoms.
