We have similar issues here and have seen a dietician who has confirmed texture aversion (most likely caused by reflux, which appears to be quite common it appears) which has caused all sorts of problems as meat is her biggest issue and she ended up severely iron deficient. We've also got the added complication of food allergies and possible intolerance meaning a severely restricted diet anyway (nuts, dairy and wheat are all out right now). We don't have the purée only issue, but only because we did BLW, and I thank my lucky stars for that one small mercy on a regular basis!

I've done a couple of things which have helped a bit. Firstly the chiro looked at her palate as she had a pretty strong gag reflex. On the two occasions she had it adjusted I noticed a massive difference in her gagging and as a result she will now eat some foods that she would point blank refuse previously. Secondly, we have done some texture therapy - not related to eating, so gradually persuading her she really didn't need socks on all the time, stroking her face with fabrics and talking about the feel, mixing cakes with her hands, putting her feet into bowls of dried lentils, rice etc. Thirdly, we go through this 'game' with her eating - 'can you touch the beef with your finger, well done... Can you pick it up in your hand, wow you're so clever, can you touch your lip with it, well done, can you lick it?' At this point, nine times out of ten she now takes a bite, chews and swallows and gets a huge cheer. Recently she's started doing this process herself without prompting and giving herself a cheer. Not how I particularly want to parent but I never envisaged ever having a kid who is fussy over food and certainly not who has suffered some fairly severe health issues because of it so I'm happy to do it for the results.

It's been a slow old game, and frustrating often, but I am noticing small results over time... baby steps. I'm not sure if this will help all of you, but if you're considering sensory issues maybe it will. Just wanted to post and say that I feel your pain though.
