My DD had pretty severe MSPI (and likely other issues, which we never fully figured out, despite my crazy elimination diet for 12 months). I'm due with #2 in less than 2 months, so I'm starting to think about whether we will go through this all again. DD was a really fussy baby who never slept well, even as a newborn, and we discovered her MSPI at 3 weeks. I've always wondered if the MSPI contributed to her early fussiness.

I'm wondering if I should eliminate dairy a month ahead of time for this LO, on the chance that he might be affected and in hopes that he will be healthier from the start.

Has anyone done this? Worth it or not worth it? If I eliminate soon, I'd probably try to re-introduce when he's a few weeks or a month old to see if it has any effect.
