tips on weaning

My baby is 1 year old. I need tips/advice on how to stop breastfeeding. She likes to drink regular milk but does not want it when she takes her naps. I have been off of work for 3 months so shes gotten use to just having it whenever she wants. I will start working full time soon and think stopping will be easier for all of us. Any of you ladies have any tips? Like should I just breastfeed at night? Or completely stop? Help please.
