I haven't shared anything since my littlest man was a week old... he's now three weeks old! Still going strong with breastfeeding. And it is a whole lot less painful than it was in the beginning. Lefty is a little more sensitive than Righty though. And at his one week check up, he gained 10 ounces from birth weight and over a pound from the weight he was at when we were discharged.
He also knows when I'm going to pump... he wakes up and demands to be fed.
