I worked with a Mom who used premarin cream for several weeks when her child was young (perhaps age 2 weeks through 6 weeks). At that point Mom was weaning off the pump after a rough nursing start (latch issues) and baby was exclusively nursing. She definitely had a humongous milk supply and a healthy, well-gaining child in the 90th percentile. Premarin made no noticeable impact on milk supply in this case. However, I do feel that women respond to hormones differently. I've known Moms whose milk supply really suffer on the mini-pill and others who do not seem impacted. Of course that is not estrogen, but I wouldn't be surprised if estrogen has varying impacts person to person as well. If the Mom chooses to use premarin, she could stop using it if she notices a decrease in pumping yield.
