Colic- dairy allergy?

Question

So in attempt to figure out what is wrong with my colicky baby I have completely cut out dairy. It’s been a week today. She seems to be a lot better finally the last 2 days, but has also been on Zantac for 3 days now.. so I believe one of the two is working. 
Say I try to introduce dairy again, and I can tell it is what is affecting her it would take another week+ for it to get out of my system right? 
I am a huge dairy person so it has been hard but I am obviously willing to do anything it takes to make my baby comfortable and happy. I am just afraid to even attempt to reintroduce if it could make her scream in pain for another week. 
(I will add her pediatrician does not think it is allergy related because she doesn’t spit up often and her poop is normal) 
I really want my dairy just so worried it could hurt her again 😩

Answer

They can do a simple test on her dirty diaper to tell you if it's a milk allergy

Answer

When I was convinced my daughter had a dairy allergy (she did not), most of what I read said it can take 2 weeks to leave your (the mom’s) system.  Based on that, I would try to add dairy back in.  You can always remove again if things do get bad again.
