(Sorry.) Low estrogen levels during breastfeeding can lead to vaginal dryness. But don't worry -- a little lube can go a long way. Use a water-based lubricant (like AstroGlide or KY Jelly), and take it slow as you get back into the sack postpartum. Erin van Vuuren | July 13 , 2010 12:48 PM Want to participate?
