I'm hoping I can find someone who has had an MSPI baby followed by one without. My DS #1 was extremely MSPI through 2 years. He was 8 days old when he started screaming and had a diaper full of blood. At the time, I didn't know about MSPI and had had lasagna the night before. Over the next 2 years, even whey or a tiny bit of butter in my diet would set him off. I went into my second pregnancy just assuming that I would have to deal with it again.
My new baby is 3 weeks old tomorrow and with the holidays, I slipped up a few times and he seemingly has had no reaction. I haven't had milk or anything super cheesy, but have had butter in baked goods and some yogurt. I am dealing with a bit of oversupply and he has had 2-3 green or mucusy poops, but overall yellow and seedy. The only rub is that he is extremely gassy and suuuuuper grunty at night. I don't know "normal", so is this potentially a warning for MSPI if I let loose with my diet or is it more likely oversupply/ typical baby gas? When did you know you were in the clear?
