My daughter will be 5 months old tomorrow and in the past two weeks I have noticed I do not feel as full. After a lot of research it seems this eventually happens. I have never had a problem getting out at least 5oz per pumping if not up to 8. Suddenly last week I am lucky to get out 2oz ever 2-3 hours. My daughter has been sleeping 10 hours a night since 9 weeks and now has now been waking up through the night ever 3-4 hours. I would BF her, but last night BF was not good enough so I had to use some of the freezer supply. My concern is even though I have a Medela PIS Advanced It seems to have lost some of its suction. I still get let down when I pump and it still seems to function ok, but I can't understand why I suddenly lost my supply. I mentioned my less full feeling to the pediatrician 2 weeks ago and she said that since the baby is 50th percentile there was no concern, but she had always been 75th percentile I am afraid she has not been getting quite enough for a little while. I bought Fenugreek today to try and I have been BF and pumping at least 10 times a day for 3 days with no increase. Does anyone have any other suggestions? I have also heard that sometimes your body can no longer be fooled by a pump does anyone know more about this, do I need to rent a hospital grade pump?
