Baby would rather sleep than eat

My daughter is almost 4 months and the past week or so she would rather sleep than eat.

She usually eats about every 2 hours and has a eat, play, sleep schedule.

So going by her cues and schedule, she is pretty much hungry about 2 hours on the dot.

Lately though, she screams and cries when I try and nurse her even though she is rooting.

So nursing sessions end with me holding her (trying to console her) and she ends up falling asleep.

Is this normal at this age? Has anyone else gone through something like this?

I’m totally baffled by her lately 🤯 but I’m also nervous that her not eating like she should is going to affect my supply.
