Why does my 2 year old hate her nan?

me and my mother havent seen eye to eye in over a year. my mother who is 62 has become obsessed with botox, clothes, men, and is generally quite egotistical, it seems she prefers all this shallow rubbish to getting to spend more time with her only grandchild, my daughter. i dont expect anything except maybe for her to take her for one morning a fortnight, to bond with her, but its never happened. my mum has been great bringing us where we need to go as im only learning to drive, but when we are getting out of the car, my toddler screams when my mother so much as helps her or even tries to kiss her. my mum has a busy life so i think its just they never really bonded and in fairness my mum has done all her childrearing. now its my turn. but im just sad that my mum doesnt even want to try and fix this. she is too busy fighting with her sister or boyfriend or shopping or something...ive expressed my anger to my partner but he feels she willl grow out of it. its getting worse and its been like this since she was 5 months old. what can i do? she really cant stand her own nan and its breaking my heart
