Are any of y’all avoiding certain foods?

I spoke with a lactation councilor awhile ago and she told me I don’t need to avoid anything..

however, I’m afraid what im eating is causing my baby to be colicky and/or fussy...

For example I ate pizza one night and it gave me heart burn... I didn’t think anything Of it but, that night my LO was up all night fussy and gassy.

I started a little book to write down what I’m eating throughout the day and also to jot down how he is. That way I can see if there’s a pattern..

Just wanted to see what everyone else is doing & if anyone else is avoiding certain things .
