I EBF Brianna and the ONLY real symptom she had of MSPI was night waking. (When she was super young she had gas, but grew out of that one.) When I took ALL dairy out of my diet that was when she started to sleep through the night (and if she did wake up it was only to find a passy and then fall back asleep. )
Anne has a lot of experience with this. You can look through her old posts or pm her maybe. She says that Lucas’ main symptom of intolerances were nightwakings. Good luck. Nightwakings are horrible. We’re in the same boat and trying to sort things out, also finding that the meds don’t make a difference but afraid to wean them off.
