My MIL is visiting next week and i need help!!!

My problem is i do not want her to touch my baby !!!

My husband and i just had our first baby (3 months old now) and my MIL is coming from France to do a roadtrip across the US and stops 4 days here to meet her first grandkid. She does not even really care about the baby, she never asked one question during pregrancy and since she was born. All she cares about is her son, my husband which she is obsessed with.

She always has been very mean to me, ruining my wedding day, talking bad about my family who were so nice to her, and basically ignoring me for the past 6 years.

She is very toxic and tries to talk bad about me to my husband. I have nightmares about her and been hurting for the past 6 years because i was so hoping to have a good relationship with her.

Anyway, now i have my baby who i love more than i could ever explain and i do not want her to touch her !!!! I know she is going to but i dont know how to handle it!!! /
