Did your LO's sleep improve after eliminating allergens?

Yes. From 10-12 times a night to 0 times a night. But for some it's a matter of removing one offending food, and for others it's a matter of removing 10-15 foods. Is sleep the only issue?

hmmm......well he also has a chronic runny/stuffy nose and we battle the occasional diaper rash.....

no hives/vomiting/eczema

Then it may be intolerances as opposed to allergies. runny/stuffy nose is often from dairy. Rashes can be from anything. The top 4 are dairy, gluten, soy, corn. Start a food journal (write down everything he/you eat [if BFing], including supplements, drinks, etc. and all sympoms [rashes, poop habits, stuffy/runny nose, sleeping, mood, etc.). Look for patterns.

Yes, night time issues improved, but only after removing gluten and dairy at 18 months. He was finally able to go to sleep without extended torturous inconsolable bouts of crying, and he didn't wake up with the same abdominal pain all night long. He did however, still wake up all night long!

We had to both take out foods he was intolerant of, and supp to correct his magnesium deficiency. Oh, and take out salicylates, he was sensitive to those as well.

I'm a newbie to intolerences/allergies (or whatever it is we're dealing with). I have definitely noticed, after two weeks of ed, that ds is sleeping much better and getting there more easily.
fwiw

Oh my goodness I can sing the praises of cutting out foods for sleeping through the night! My son has been sleeping through the night for almost 2 months now (he's almost 21 months now) after we got very serious about cutting ALL dairy out - casein, milk protein, whey - his preschool teacher gave him some goldfish crackers (GGRR!) and he was up that night very restless and wanting to nurse all night which was the problem before we cut out dairy. But I don't think that sleep is going to be the ONLY symptom of an allergy/intolerance: my son had a drastic mucous reaction when he had dairy and his behavior was pretty off the wall when he had had a lot of dairy (aggressive, restless, extreme sensory seeking behaviors). Those behaviors have drastically calmed down since cutting out the dairy - it's pretty amazing to be honest. He still has his moments (he's a toddler boy so what do you expect LOL) but on the whole he acts like a different child.
