Ok I need help

do

So my son HATES anything other than a bottle and anything colder than room temp. I have tried every sippy cup I can find. Just drinking from a cup a plain straw etc and can not get him to take more than a few sips. I've tried putting milk in them and he gets VERY upset. He will only take sips of water or juice out of sippy cups. Hes got to get fluids idk what else to do
