Baby supplies for my mothers house

Hey ladies! So once I have my son I will be out for a few months but when I return to work my mother will be watching him once a week. What should I have at her house to make it easy for her? We are going to get her a car seat base, a pack n play, and the diaper bag will go with him. Any suggestions on other things she may want at her house? FTM and would love some suggestions!
