My ILs are not to be left alone with my children. They completely ignore them when we are around, I can only imagine how bad it would be if we left.

My parents, FIL, and his wife can be alone with DD. MIL cannot. I didn't announce my decision and I will not. MIL is untrustworthy and weird. She is lonely and craves physical contact to the point where she is obsessed with holding. I don't think she would ever touch DD inappropriately but I do think she would try to cuddle and snuggle to fulfill her own needs and that makes me feel sick. I observe her doing this with her other granddaughter...my niece. There are too many suggestions to sit on grandma's lap. She also doesn't follow my SIL's instructions regarding food; she gives my niece junk constantly. I couldn't deal with it.

My parents are totally trustworthy. I trust them completely with our kids. My inlaws are loving grandparents who would do anything for their grand kids. But they drink at least three or four drinks every day. I worry that they might drive with the kids after drinking. For that reason, we don't leave the kids with them.

I'm the PP with the trustworthy FIL but not MIL. MIL goes ballistic if she finds out my parents watched our kid. So we try not to mention it - which is fairly easy to do bc both sets of grandparents live several hours away so it doesn't happen that often. We don't have a local babysitter but I don't think MIL would object to that. It's just my parents that she is sensitive about.

OP here. Thanks for everyone's feedback. Do your parents who you won't leave kids alone with know that you use other babysitters?
