Breastfeeding help....?

Ashley

So this is week 3 for my baby girl. She's started latching on eating for a couple minutes then unlatching and crying, grunting, squirming, tossing her head back and forth then relatching again and repeating the cycle until she gives up and just cries until she falls asleep. I can't calm her or get her to settle down but she will stop to drink and ounce or 2 of her supplement formula. Am I doing something wrong. Is this a sign of over production. (Side note: when I grab my breast to guide her latching I do squirt milk quite a good distance with pressure but I chalked that up to the distance between her feedings lately).
