My LO had a stomach bug Monday. I came down with it on Wednesday but I'm still feeling bad. I took 2 dosages of phenagrin on Wednesday and pumped and dumped until the next day. During that time I used up all my expressed breastmilk supply I had in the freezer. Now I am only able to pump 1 and a half to 2 ounces at a time. I can tell my LO is getting frustrated when nursing. He has also lost a little weight this week. Should I start supplementing. I had to go to work today and only had 9 ounces to leave for him. I usually leave 15 ounces. He is 8 and a half months old.
