Am I being mean?

My mom was here a week before my baby girl was born. She was mostly helpful. When she was born she was here for another week. She was supposed to help and keep my two year old entertained. Long story short she didn't really do much to help and always complained about being tired. It irritated me especially since she was the only one in the house getting full night of sleep. Anyway since she went home I feel irritated everytime I talk to her. We've had feeding and gas issues with the baby and she seems to have all the answers so I just keep my distance because I always get off the phone irritated. I'm not mad or avoiding her I just don't feel like talking to her. Especially because I usually only get an hour to myself a day and I want it for me. Am I being mean??
