Would you let a drug addict who came out of rehab a month ago watch your infant?

My daughters Grandmother (husbands mom) has been babysitting my daughter since she was born. She watched her 2-3 times a month between other grandparents and family members who wanted to babysit. On one occasion, a giant dent appeared on my car when she was driving my baby around. I gave her the benefit of the doubt that it was there before she took the car.

Fast forward 9 months later - Grandma goes to rehab.

Apparently a few family members knew she had a pill problem and didn’t feel the need to share that information with me. I knew she had a problem 20 years ago, but I was lead to believe she was past it. This woman was watching my child alone, overnight, and driving with her in my car.

Three days after she gets out of rehab, she calls me looking for pills that her other son left at my house. #1. Why is he hiding drugs at my house? #2 You just got out of rehab and you are hunting down klonopin.

I told my husband that she will not be unsupervised with my daughter, because I do not trust her.

Now I am the bad guy in the family. I am “trying to keep her granddaughter away from her” and I am “tearing apart the family.” I’m just trying to protect my child.

Would you let a “former” (🙄) drug addict who came out of rehab a month ago watch your infant?

TLDR- Grandma who just got out of rehab wants to be trusted alone with infant.
