Confusing .. attachment maybe ?

So.... I think my daughter might be lactose intolerant. I been trying to use new lactose formula with her today and she was just crying non stop even though I knew she was hungry . And I could tell she was hungry because she will always suck on her hands. But she would NOT take her bottle . She was just freaking out. So I decided to just breast feed her. She’s now so very calm and no fussing or crying at all. Is it just attachment ? It’s crazy how much a bond we have. And I adore that she loves me so much .
