When I feed 7 week old dd at around 6pm, she squirms and wriggles and grunts more than normal and tugs my poor nips until she's red in the face and I'm red in the boob. It really seems more pronounced than at other times of the day. She is then unsettled for a couple of hours until next feed. I had thought this was due to wind, but it occured to me that perhaps my milk supply was less at this time of day and she was frustrated trying to fill up on it. Anybody wise enough to help on this?
