would you be mad?

I can't tell if it's my hormones from starting my period or if I should be genuinely mad. My baby tends to cry a lot which is fine for me bc I don't mind tending or trying to figure out her needs. My MIL on several occasions has mentioned that my baby has mal ojo which is just basically "evil eye" in Spanish. She keeps wanting to run an egg over her to "cure" her. I have told her no on 4 occasions that I can remember although it has been more than 4 times. I have told my husband this and he's fine with my decision. Well I guess the other day I left the baby with him, she was crying more than he could handle so he calls his mom to "cure" her with an egg. He told me when I got home and I got super pissed off. I don't believe in the magic of an egg. And the fact that he just couldn't handle her crying pisses me off. I was gone for no more than an hour and mil usually stays for two hours. So they did it quickly before I got back bc they both knew I wouldn't approve bc mil was gone before I returned. Is it hormones or should I be mad? Also baby is still the same so clearly the egg didn't work
