tbh I don't have a clue, but I can imagine it has something to do with either a growth spurt or teething!
from a bottle it is far more easy for them to drink, whereas on the breast they need to put in some effort!
both teething or growth spurt could be something what makes your LO kind of too lazy to feed from the breast!
rule out any pregnancy and possibly don't give the bottle anymore?
when they are older they start to look around whilst feeding as feeding gets a social activity
