MIL has fell out with me
My MIL has fell out with me because I expressed concern about her giving my recently turned 5 month old ice cold filtered water out of a glass (no sterilisation) - behind my back despite me politely telling her beforehand that he’d never had water before and I’d prefer for her not to give it to him yet. (For context I walked in on her doing it btw so I saw it first hand and was absolutely shocked). She yelled in my face, completely snapped at me, told me she’ll never do anything for me again, was sarcastic about her changing his nappy and said she hopes I don’t have a problem with that either. I remained calm during the whole exchange despite her giving me evil stares and rolling her eyes multiple times and just being rude. She stormed off and has refused to speak to me since. I sent her a message the morning after to check if she’s ok and that I’d love to restore our relationship but she’s ignored it (not like her as she usually responds immediately). My husband is abroad atm so he’s not around to mediate. I’m really keen to repair this and get back to normal but I’m not sure what else to do at this point.
Anyone have any advice or tips?
