Try changing bottles and put a couple drops in the mouth before putting the bottle

@josee152024, his mouth is clean inside no thrush!! Pedi changed the milk formula as well :(

@bebe-, i do try to feed him but he pushes the bottle away or nipple with his tongue

Check his mouth inside the cheeks for thrush just to rule that out otherwise maybe bring it up to his pedi/dr

@bebe-, he is about to be 3 months!! He feeds every 2 1/2 hours and cries before every feed. At night he drinks no bother
