Been watching this thread, and now am all caught up. All the advice you've been given is so great, I can only echo that, and offer hugs!!
I am SO happy that you've shortened the mealtimes, as this really will remove any pressure from both of you, and you can start fresh.
I also agree that the solids aren't as important right now...just keep offering them, they are more for experimentation than anything.
Oral motor issues are so common, and so treatable. There are very few pofessionals who fully understand them. In the US, there is something called early intervention, where a speech therapsit will come to the house and watch the child eat, suck, and swallow, as the way a child does any of these can be very telling. It seems to me that since your lo ate different textures at one time, that perhaps an oral motor issue may not be the problem? I'm thinking that if she did have motor issues, that she never would have accepted that food in the first place. Just thinking out loud here. If she does have oral motor issues, the sooner she gets treated the better.
I found with my dd, she definitley had some texture issues. Sometimes she'd refuse food, but take it if I allowed her to feed herself. Sometimes she's refuse something if I cut it up, but would happily eat it if I gave her the whole thing (like a whole apple instead of chunks I cut up). Sometimes she wanted it on a plate, other times right on her tray. Sometimes she wanted to use a spoon, sometimes her fingers. It takes alot of trial and error.
I too, have lived with an eating disorder, and many members of my family have as well. I am determined that food will not be an issue for my dd, so I understand your position on that too. In my house, food has nothing to do with rewards, punishment, or entertainment. I do try to keep her diet low in sugar and in salt, but that is just because my mom created 5 suger junkies!!
I do hope you can get some answers or at least some attention from these doctors. If they blow you off, just say "You'd better get very used to the sight of my face and the sound of my voice....because I am not going anywhere until I get some type of help."
It seems as if you were making some real progress there before she got sick...that's wonderful!
I will be lurking and hoping for more success for you!!! Remember that your girl will feel your anxiety...breathe Mommy!!! I promise she will not starve herself. This will pass....one way or another, whether it's a power thing, whether it's an oral-motor issue, or even if it's just that she wasn't ready for solids just yet and you end up just going backwards for a while and doing more of a BLW approach....no matter what, it will pass.
