Question for breastfeeding moms

Breastfeeding moms of babies who have a milk allergy. After cutting out dairy how long was it until you saw improvement?

That didn’t help for my daughter……there was a specific protein in milk as well as other things like pork and chicken that she was allergic too. I had to cut it all out before we saw a difference we saw a difference right away once we figured it out with in a few days she seamed calmer more relaxed happier it was night and day….we ended up having her allergy tested when cutting out dairy didn’t help that told us about the protein allergy.
