Milk allergy - anyone with any experience on this? We just got diagnosed

FirstTimeMom💁🏻🤰🏻🤱🏻

My 9 mo baby who is exclusively breast fed just got diagnosed with a milk allergy but the doc didn’t tell me to stop my diary intake. I am so worried - anyone have any tips ? I really hope he outgrows it 🙇🏽‍♀️ did your kid outgrow it? What age ?

I don’t limit my diary at all and his poop had been so gooey not sure if it’s mucousy and he seems happy and fine otherwise speaking.
