Oh you poor thing, that does sound like something that would just weight on your mind and cause stress

My DD1 had a oral sensitivity issue when she was younger than your DD. Basically she didn't like anything in her mouth, she really didn't like spoons in her mouth but once it was pointed out we realised she never chewed on her teething toys the way they were intended, pretty much nothing harder than yoghurt got any further in than her front teeth. It sounds silly now but even eating yoghurt she would try to lick it like a cat instead of letting the spoon in her mouth. We saw a speech pathologist and we had some different toys and exercises and ways of feeding her and we managed to desensitise her mouth I guess you would say to the point that she would allow cruskits and spoons and toys get in there. She was (and still is) a crap eater but now it is just her being a little turd, not the sensitivity causing it But my point is that for us it was something that once the right person gave us direction it was relatively easy to fix.

The gagging sounds similar to something that DD2 has going on. She has a floppy airway that means she does tend to gag and choke on foods way more often than the average kid and it was taken a looooooong time to get her into foods that are more solid than mush. Has your DD even had tests for anything like that? We have just been told it is just a case of the airway being a bit 'immature' and she will grow out of it at some stage, most likely between now and 2yo. I mean she is keen to eat so it not the same problem, but her airway just gets in the way and often she seems cautious with some foods, I assume because she knows they might make her gag.

Both of these things are things the paed will be able to shed more light on and help with. Good luck....x
