3 months in and baby is suddenly not latching

My baby is 3 months old and she’s been breastfeeding from the start. I have a good supply and she has a good latch. But recently as of about 2 weeks ago she cries when I go to lay her down across my lap to feed her. I’ve tried just leaning her, sometimes I have to stand up and latch her like that but she cries. I don’t see any sores or injuries on her. After a lot of effort she’ll latch and eat. When I don’t fight her so hard thinking she’s not hungry she has a meltdown later on. Has this happened to anyone??

Edit: she only really eats without a fight in the morning after she wakes up, during night feedings, and before bedtime if she’s swaddled
