No dairy🤷🏼‍♀️

Hey ladies! So i’ve been struggling with my baby having reflux and constant spit up that makes me do laundry everyday and I can’t keep a clean shirt for a day either type of spit up. I’m currently breastfeeding and she gets bottles of breastmilk at nighttime, with a slow flow nipple and still seems to be gulping and spitting up soooo much. Long story short I hate not knowing what’s causing her discomfit in her tummy, I can see her squirming while sleeping and grunting from gas. Has anyone experienced completely changing their diet to non dairy products and finding that to help? If so is every product you eat/ drink non dairy? Or any other suggestions from moms that have dealt with severe spit up in their little ones!

Also her doctor is not concerned because she’s steady gaining weight and having normal wet and dirty diapers.
