Pls try to change feeding positions as well. I experienced same issue and side lying position helped him in sucking better

Colic could be one reason and if baby is 4months plus u can start top feed also

Hey try cooling him first and then feed again ..you can increase the frequency if possible ..sometimes they are sleepy and hungry both so they cry ,or any other reason of discomfort please check and stabilise the baby first then feed in a comfortable position.

also chk if baby has cold his nose might be blocked. in that case pls steam. take baby to dr. ask if u can use nasal saline drops
