Help. Have been having trouble satisfying DS since before xmas day. Ds is now 11 weeks old and at his 8 week check his weight gain had reduced to the point where the doc was worried even though he had gained weight. DS was 6 weeks premature and his weight has always been a concern with the docs - I had posted on another BF thread about them pushing formula. I am an almost full time pumper with one or two full breastfeeds or snacks a day. Even pumping I am producing much less each time - and I mean about 60- 80 mls less. Yesterday I had to give him a bottle of formula as he was screaming the house down and there was no more milk either when I put him to the breast or with frequent expressing. He was lethargic and appeared a little unwell but perked up immediately after the bottle. It gave him chronic painful wind later though. Today I had to give him one formula top up to make up a full feed. I really did not want to do this, neither did my partner and we are unhappy about it. I have been scouring my books for advice and assistance and came across a section about inadequate milk supply which stated that one indicator of reduced supply is the return of periods before baby is 3 months old because it indicates a change in the level of hormones in the body. I got my period when DS was exactly 6 weeks old and have it again now. Could this explain my reduced supply? Is there anything else I can do other than frequent pumping/feeding to increase my supply as currently this does not seem to be having any effect. Does the return of the dreaded monthly cycle mean that I will not be able to fully breast feed DS. Am feeling very down.
