I think it worked for my DD, but it doesn't mean the same diet will work for everyone too. I'm guessing in her diet something was not settling well with her, but to this day I don't know what it is, and maybe for your LO it's a totally different thing.
I think doing a food journal definitely made me be able to point to certain things - food colourings and food additives. But I couldn't pinpoint anything else.
What also really helped is that she is now in preschool and I have to pack her lunch, whereas before she was at daycare where they provided food - and their definition of healthy is not exactly similar to my definition of healthy, yk?
I used maple syrup and I used a bit more than the recipe calls for (to entice my DD into eating it
)
As for how to get her to eat those things... she won't drink broth on its own but I cook a lot with it. she doesn't like sauerkraut either but loves pickles so I bought traditional fermented pickles that are unpasteurized and I keep meaning to try other fermented recipes but am running out of time! apparently fermented carrots are good too. for us it was a slow move, we needed to adapt to DS's intolerances (low starch, low sugar) so that I wouldn't have to always make 2 meals and 2 snacks and so ended up having to make everything from scratch. I needed to tweak a lot of recipes that were safe for him to get her to like them but with lots of tries we were able to find recipes that she liked. and some items she's just dropped from her diet - for example regular yogurt, I make my own now but no matter how much I sweeten it she doesn't like it, I just don't buy the regular one anymore and if she doesn't like mine, she just doesn't eat any.
I'm in no means saying that it's a miracle cure, but it's helped her. and it's a process. it took a few months, and we went gradually. but your DD's diet sounds great, maybe it's not about diet for her, yk?
my son is 21 months and he does eat all these things, but he's been used to them for a long, long time. everything else hurt his tummy so he caught on quickly which foods helped him feel better. broth and sauerkraut juice in a bottle is a treat to him.
both my kids take the gutpro probiotic (available in the US)
and no, I've never tried enemas and also shudder to think. my friend uses enemas with her daughter who has severe issues and is following GAPS, but honestly, I'm not too interested and I don't think DD would ever allow me to do it.
