My DD is 4 mo. old now and so far bf has been going fine. I don't have to pump much b/c I am a SAHM but I do pump occassionally (about once every 2 wks or so) if I will be out w/o my LO. DD usually only nurses on one side at every feeding so up until about 2 wks ago I could just pump from the side she didn't nurse on and get 4-5 oz of milk in about 10-15 min using my medela manual pump. The last couple of weeks, however, I am having trouble getting even an ounce or two when I pump!! DD seems to want to nurse a little more often during the day and night too and sometimes will now take both sides during a feeding. Should I be concerned that my supply is dropping? DD's diaper output is unchanged. What can I do differently to get a full bottle when I need to go out? Thanks!!
