what d-mer?

Cause I am in the process of trying to cut out all dairy and OMG its going to be hard. Have swapped to soy, but alot of meals i cook have small amounts in it. How far do i go?

DD is a very grumbly/rumbly tummy girl and pretty unsettled. She is though only waking once a night. I didnt think I ate alot but looking into it , its in most meals without even thinking.
