Baby father side issues😒😭

Brittany • Just wanna be a good mommy
My ex mother in law told me yesterday that I wasn't smart enough to have a baby and she wants custody of my daughter.. But I have a whole house and car and a job and goes to school... So I was wondering how wasn't I smart enough.. She used to call her granddaughter ugly until I told her to stop.. WHAT TO DO I DONT WAN TO GO TO COURT AND DONT WANNA LOOSE MY BABY😭❤️
