Here I am!
If I remember right Olly has always had bad gas that keeps him awake at night hasn't he? Have you ever had 'a good patch' or has something always been troubling him?
As Eloise said I have a feeling that J has fructose malabsorption. We still haven't had it confirmed yet (a combination of DH not realising the extent of the situation until recently
(since he's been fine for months and months now, but because I'm only feeding him things I know he can tolerate) and dietitians being hard to get appointments with after our earthquake) but we hope to get an appointment sometime soon!
Anyway, Olly's diet actually looks quite similar to J's. The things that stood out as high in fructose are:
Apple (one of THE worst things for fructose malabsorption along with pear and honey)
Melon
and from the bar raisins and apple juice. Not sure maybe the coconut too
J's symptoms are he gets a rock hard tummy and just SCREAMS and SCREAMS. An episode usually lasts about 45mins sometimes a bit longer. Thankfully they are rare now (though DH wants to do some blind trials where he feeds J pear without be knowing so that my interpretations aren't biased (he wants to rule out the placebo effect), so I'm expecting to deal with it again soon
Ugh DH!) but I found them really horrible and heartbreaking to deal with.
I think we see the consequences of a bad food within a few hours. Probably up to about 12. The other day J swiped E's pear at 5pm and at 3am he woke screaming which is so rare for him. Back when he was younger we used to give him a tiny bit of pear with his losec for reflux morning and night. He would have a screaming attack in the night every night then as well as in the mid morning.
Is he allergic to wheat rather than just intolerant? Because it is very common to react to fructose and wheat I believe because wheat contains fructans which are related to fructose. But that would be intolerance rather than allergy.
Here's some info I have found about fructose malabsorption
http://www.healthhype.com/low-fructose-diet-in-fructose-malabsorption.htmlhttp://www.healthhype.com/nutrition-guide-for-fructose-malabsorption.htmlI also found this one the other day
http://www.thefartingpear.com/index.php/fminfo which is quite easy to understand and has a pretty nifty food search tool.
There's someone else here, Ali from Aus (fireredjewel) who has fructose malabsorption and has helped me out a lot. She's the expert!
Hope that gives you something to think on and perhaps will help as you look for patterns.
