Dairy allergy/intolerance—I feel terrible

Any other moms out there whose babies have dairy intolerance? I’ve had to cut out all dairy from my diet. Baby’s symptoms were milk diaper rash, gas, reflux, discomfort/fussiness.

Since cutting everything dairy she’s been great! I slipped up the other day and had some food that had dairy in it. I feel like the worst mother in the world as some of her symptoms returned. I’m hoping it does not take another 2 weeks before she’s better. I feel horrible
