I posted a related question in the working and breastfeeding area, but I was wondering if anyone is in the same position. For the past month or so, I've been having trouble pumping enough while I'm at work and have been sending ds to daycare with 5 oz of formula in addition to (usually) 10 oz of bm. However, I don't feed him any formula on the weekends, I just nurse him on his regular 'schedule'. Shouldn't my supply have decreased since I'm supplementing during the weekdays? He doesn't seem extra hungry or anything on the weekends, and he seems to consume a normal amount at daycare (ie I don't think they're overfeeding him or anything.) Does that make any sense? Its so frustrating having enough on the weekends but not on weekdays.
