I didn’t want my mother in law at my house

Am I cruel for telling my mother in law that I didn’t want her coming to the hospital or to me and my partners house until my newborn daughter reaches 4 weeks i want the time to be with my husband and to adjust to this new life as I feel having guest is going to mentally drain me as I’m someone who gets drained pretty easily his mother chooses to only care for gender reveals and baby showers and to check on her grand child she doesn’t seem to care about how I’m doing or feeling and I know it’s her grand child but I just want her to wait till I have the energy and strength to be able to mentally handle her
