Had one of five with night terrors. EVERY night for 2 years. Someone told us to make sure he wasn't getting nitrates/nitrites in his diet (deli turkey, hot dogs, bacon, etc.) We cut those out and within 3 nights he was sleeping through the night. Just to make sure it wasn't coinsidence a few weeks later I gave him deli turkey. . . . NIGHT TERRORS. He finally got to a point around 5 or so that occassionally he could have those things again but even now at 10 I can tell when he's over eaten nitrates/nitrites.
