Anxiety being away from baby-9 months old

My daughter is 9.5 months. I have only left her with my husband or my mom (at our home) for max 6 hours while I work 1-2 days/week. Even when I do leave I am frequently checking the monitors to make sure she is okay. My MIL asked if she could take baby for the day when she is around 11 months old. I said “I’m sure that’d be fine” but internally I am panicking. She raised 4 sons and has two other grandchildren she is good with. But I have such anxiety about this. I don’t like the thought of anyone driving my baby around or her being outside of the house without me. I picture the worst things happening or her crying for me and I’m not there and I can’t check in on the monitor. I don’t know when I’ll feel ready😞 Is this like a bandaid I just have to rip off or should I wait until I feel ready? I feel like 11 months is reasonable I just have anxiety 😞
