Dr told me it's all coincidence and that my baby isn't allergic!

So, met an allergist today and she told me that I can eat anything/everything (EBF) and that my baby isn't allergic or intolerant to anything.

She said that the positive CMPA test was a false positive and that she isn't allergic to cows milk. She said that it's also a coincidence that my baby always get sick when I'm eating potatoes or egg (tried to introduce 3 times, with weeks apart). Main symptoms are projectile vomiting, blood in stool and weakness.

Not only did she said that I should eat everything, she also told me to give potatoes to baby and start solids early because she has actually lost weight...

On top of this she prescribed esomeprazole and sent us home with an follow up in 4 weeks.

Now I'm completely lost...

I really thought baby was fine, cause she hasn't had any symptoms when I've had a restricted diet. Now the weight loss made me so sad...
