Lily has always yanked a bit in the evenings, I'm assuming due to lower supply. The last month or so, she's pulled on and off throughout lots of her feeds, looking backwards as if there's something more interesting. If people come in and talk to me or I feed her in public it's worse. I worry that it's my supply diminishing but she doesn't seem distressed and still has all the good signs (wet nappies, active etc) Any ideas? It's making some feeds difficult and long (I try to give her 20 mins on)
