Please help

My son will be 3 july 1st. He doesnt care about anything he has absolutley no fear and doesnt listen at all no matter what. Ive tried time out ive tried little taps on the butt ive tried taking toys away tried the corner.you name it ive tried it. He really just doesnt care. He also throws the biggest trantrums. He hits and bites me. I have another son who is 5 and he never ever acted this way. Idk what to do 😣
