I have recently returned to work three days per week and have been pumping every 2.5 hours while I am away from my baby. Ever since he has started taking the pumped bottles, his stool has been green and he has been fussy at the breast. When I am with him, he usually eats ever 2 hours during the day, but only from one side each feeding. When I pump, I pump both sides. Am I creating an oversupply by pumping more than he normally eats? I think he is getting too much foremilk causing the green stools. Should I alternate sides each pump session to mimic what we do at home?
During my work days I usually get about 18 oz (4-5 oz combined per session) He consumes about 12 oz during the 9 hours I am away from him.
I've also been pumping once in the morning on the days I am with him.
I am trying to think of a safe way to reduce my supply so he is more comfortable and getting the nutrition he needs.
