4mo seems like he hate his bottle 🤦‍♀️

I bottle feed my 4 month old 1/2 formula, 1/2 breast milk. He’s always been a snacker, never really finishing a bottle...but he would take a few ounces here and there without a problem. Recently it’s become way worse. He’ll scream and thrash and turn his head like I’m poisoning him after just a few sips, but then if I take the bottle away he freaks out like he’s starving to death. The only time he eats nicely is in his sleep. If I wait till he’s napping to offer a bottle, he sucks the whole thing down quick and easy. He’s definitely not losing weight, he’s gaining nicely, but feedings have now become stressful and messy and take forever. 😩

Can anyone relate or give advice?
