My house is an alcohol free home I don’t allow alcohol or people who have been drinking into my house for personal reasons. I live with my partner and our son. My MIL is staying over soon and knows my feelings towards alcohol the day she is staying at ours she is going out for a meal with her friends which will involve drinking. Had I known this before she would not have been invited to stay at my home. I don’t want her coming into my home having consumed alcohol or holding my son. She lives abroad and doesn’t see us often I thought it would be safe to have her here as she was meant to be spending time with my son and partner while she was here as she’s only here 2 days I don’t know what to do.
