I've been pumping since my LO was about a week and a half old (he's 6 & 1/2 weeks now) to get a supply of breastmilk in my freezer for when I go back to work. I usually pump after he eats and still get anywhere's between 4 and 5 ounces at a time. I recently (about a week ago) introduced bottles to him to get him used to them for when I go back to work, I pump around the same time I feed him the bottle or as soon as I get home. I only give him MAYBE 1 bottle a day if I go out in public and can't feed him (I'm not a pull my boob out anywhere's kinda mom). I try to give him the fresh breastmilk in the bottle for now instead of digging it out my freezer, I pump right before we leave to bring it with us, and the past 2 or 3 days I pump and only get 2 ounces at a time. Is this something I'm doing wrong? I can pump all day and freeze the milk and swear I can pump a gallon of milk when I'm just freezing it but when I NEED it to go out I can only get 2 ounces?!?! WTH! Anyone else have this problem? What can be causing it?
