Tips for baby that hates bath time??

E
My son is 10 weeks tomorrow and HATES bathtime. I keep the temperature warm (I have a digital whale thermometer that floats around and let's me know if the water is too cool/hot). I tried making sure the tub was covered in warm water before putting him in. I tried a warm washcloth on his belly. He literally just screams the entire time ☹️
Any tips?
