Eliminating Dairy

Ms.Dancer03

My 2nd DS is almost 6 months old.  From the beginning, my husband and I just thought he was a 'fussy' baby and he would outgrow his tummy troubles.  He cries ALOT during the day, and generally seems uncomfortable, like his belly hurts.  His is EBF, and I am finally thinking maybe it's something in my diet?  Everything I'm reading says to start with eliminating dairy.  Has anyone had luck with this?
