My baby is exclusively breastfed.

I'm not sure what's going on he's crying like he's hungry but won't eat, hes pulling on my bra like he normally does when he wants to nurse but when I pull it out and put it in his mouth he just stares at me confused. Like wth you know what to do!?!? He won't even latch ¿ sometimes if hes not hungry he'll latch for at least 5 min but not this time, he's 7months so it's not like he forgot how to nurse. He won't take a bottle or paci. GUYS IM SO CONFUSED AND DONT KNOW WHAT TO DO

LITTLE UPDATE!

He makes a grossed out face when he tries to latch, I decided to cleaned it maybe its sour ¿ idk but nothing changed he still makes a grossed out face.
