Opinions please

So my baby boy is 2 weeks old, my husband and I live 1,000 miles away from family. His parents are here visiting now & my mother in law (who I love, it's not a bad relationship lol) offered to keep my baby tonight (one room over) so that I can get some sleep. I let my mom do this once while she was visiting last week & all was fine...but I'm a little more nervous with her than my mom just because I know better how my mom is. My husband swears it'll be okay & she has kept her other grandchildren many times I'm just a worried new mom. What would you do? I know that she will care for him exactly how I ask, but I just need to know if it's wrong for me to allow or stupid. I'm a super worrier...so I would love opinions lol
