LOL at sucking through your shirt!!! Matilda would feed on/off for 4 hours straight and then sleep for a little while & want to feed again when she was 6 weeks. She was like clockwork, but would do these cluster feeds where she would stay on for hours & then come off for 2-3 and then back on for hours.... I think she sipped and slept LOL. It was painful and frustrating when all you want to do is make a coffee or go to the toilet, but you are doing a great job!! I'll be remembering this in a few months time
