what to do?

Who else breastfeeds and formula feeds their baby? I breastfeed when am awake and when am sleeping, his dad or my mom feed him enfamil formula. He drinks both and doesn't care but I need to increase my breast Milk. I work during the night and sleep during the day and I do pump but I miss it when am sleeping. What else do I do? Do I have to wake up every 2 hours to feed or pump to increase my milk?
