Sleepless29,
I want to share my experience with you also.
When I have my 2nd child, he was unable to latch so well till 4 month i go to work and I also do pumping every 2 hrs or 3 hrs inconsistant. Depend 2 or 3 hrs lah. My supply alway at 20ml only. very less but I message to pump at this amount till my child reach his 9 mths ol. Of course my supply was not enough for my boy, so sub with formula milk.
Then, I have a third boy which is very good in latching . So during my first born till the first 2 mths. I latched on every 2 hours and pump at the same time when latch on. If baby never consumed milk, i pump 2 hrly of 8 times a day/nite. Then, my supply comes in after the 2 mths of hard work. I cant remember how much i pump, it should be around 1 big bottle of 250ml for the start for both breast combined (250ML). Then, it increases both breast each 250ml at 3-4 mths. I also latch on one side and pumping concurrently. It still reach 250ml. You may tried this.
Then, I start work on the 4mths onwards, trying to reduce some milk at 5 mths, it drop so fast till i though it went missing....and asking for help here..
Some advises, if you keep thinking of 20 ml only so less and so stress no milk....then this is a Stress for your body and milk that wont help you produce milk. people alway say must relax so that milk will come. Try to relax when pumping , dont think of anything. Can watch TV or something else. Next is the timing. You must fix your timing for pumping, why, because the little pain may come to inform you that the milk is flowing out the breast. I lost this feeling already due milk when low. Fixed your time at even hours or odd hours. "A MUST."
Good Luck. Jia Yu!
