I am new to forums and new to bf and pumping. I have to return to work the first week of August and must store enough milk in order to return to work. My baby is 3 weeks old and i have been pumping after each feeding (8 sessions per day). I have not been consistent with the exact time i pump with each session. Should I be pumping immediately after i feed my son or should i wait 20-30 minutes after i feed him so my milk can get a chance to come in? does it matter with timing as long as i pump in-between feedings?
