hi. my 15 day old girl used to drink 80ml ebm every 3 hrs. as my supply is not enough, I started giving her fm (nan h.a.) for night feeding yesterday. but both feeding she took only 30ml. I changed to ebm and she took 70ml. but this morning, she took only 40ml ebm again. is this a cause of concern?

I had the same prob as you back then when I started latching my LO. It was a nightmare with cracked and sore nipples and nipple shield doesn't help in the DL. You can try putting on a cold Ardo Lilypad to temporary soothe the sore nipples. What I did was to exclusively pump till LO is almost 2mo and I decided to switch back to exclusively DL with my mind set to endure the pain that comes along. Reason being for my switch back to DL because I noticed a drastic drop in the amount of expressed BM and I kept telling myself the amount that I pumped out is not equivalent to the same amount when LO DL. And now, when I pump during the wee hour, I noticed the BM amount has increased a lot. Get your hubby to support you by saying encouraging words to you when you are too stress up with BF. Jia you and you will soon enjoy DL as much as I do now;)
