Care.com?

I am in a situation. My husband bought concert tickets for next Friday on a whim. My mom said she could watch our daughter, but has since started a new job and is exhausted. She would have to drive straight here from work (40 minutes), then stay until like midnight, and either sleep here or drive home. She has to work a second job early the next morning. I feel bad asking to her to this and she was open about feeling overwhelmed by it.

She is the only person we have ever left our daughter with. My daughter is 7 months old and sleep trained. The sitter would just need to give her some milk, and put her down to bed. It would require about 30-40 minutes of interaction and then just monitoring her via video.

I feel nervous to leave our daughter with someone we don’t really know. Has anyone used Care.com? We don’t really have friends why are available to come to our home to watch our daughter. She has to be at home, in order to be consistent with her sleep.
