Breastfeeding Fussiness


I have been pumping and breastfeeding my 5 MO since day one. She takes a bottle just fine but lately when nursing she will pull away and start screaming. It isn’t every time but it’s pretty frequent. She has a milk and soy intolerance so I have eliminated both from my diet and I’m pretty strict with it so I don’t think it’s due to something I ate. Anyone else experience this and have any insight?
