First of all, huge hugs to you. My second baby, Kate, had feeding aversion due to reflux pain, so I can understand some of what you are going through xx
For what it's worth, and I KNOW it is way easier said than done, but try not to worry. Kate is almost 14 months now and at this stage is really just starting to get into the hang of solids. I have a thread about our experience of her not wanting to eat solids, will look it up later so you can read the advice others gave me there. At your los age, she was not eating anything most days. Kate has thrived though, was obviously getting enough from nursing. We did end seeing a feeding specialist, who said her feed refusal was probably down to oral aversion from reflux, and that she would come good in her own time. And she did.
Some things that stick out at me from your post is that I really would limit the mealtimes. At her age, it really would not be neccessary for her to eat that many meals and snacks. We followed a pretty much babyled weaning approach, where she was offered fingerfoods to feed herself. This all happened at family mealtimes (I also have a toddler~wait, a preschooler, he is 3.5 now!). When mealtime for veryone was over, it was over for her as well. I think it would be extremely stressful all around to persevere for the amounts of time you are talking about. At that age, Kate had already started to walk and was eager to spend every waking moment practising her new skill. And even if she wasn't walking, I am sure she would not want to spend all her A time with a bowl of food in front of her. I would find it very stressful too. If you feel you are feeding her all day long, she must feel the same too, and may be at the point where she is so fed up with it all she can't even be bothered anymore kwim?
I would be concerned if she is not drinking milk though. How many oz does she drink in 24 hours? Can I ask why solids were introduced so early on?
I will post the link to my thread as soon as I find it xx
