Have you tried taking cayenne pepper? It is very good for improving circulation, I take it mixed with water and other herbs. Start small and work your way up, it also kills parasites. Turmeric mixes well with it and is an amazing herb as well as a parasite killer also.
I know some babies are sensitive to cayenne, so it may be best to pump some extra milk if you don't have any in case baby is bothered by it.
