After reading on MN that Equazen fish oil had made some children's hyperactivity worse, I cut it out of DS2's diet three weeks ago. We then had two weeks of almost unbroken sleep. When we went to BIBIC they suggested flaxseed oil. Started this on Sat and he's been awake for 4 hours in the middle of the three nights since. It also seemed to make the eczema round his mouth worse, though this could be a coincidence. I'm going to e-mail BIBIC but does anyone have any advice about anything else I could try? DS2 has quite a few food allergies.
