Am expecting my second child in a few weeks time, and am planning to breastfeed to start off with. I am currently suffering with very bad SPD (have crutches), and have been told by one of my friends that I shouldn't breastfeed once the baby is born, as this will exacerbate the SPD problem. She says it's because my body will still be producing excess hormones if I breastfeed, and my SPD will continue until I stop and my hormones start to go back to normal.
Does anyone have any knowledge/experience of this, or is it just mumbo-jumbo?
