Silly question

Ever since I have been pregnant, I only want to drink ice cold water. Like a water bottle full of ice and then I fill water in it. As soon as I drink it, baby starts kicking around. That part is awesome, feeling baby kick. But then I drink atleast 3 such bottles while at work. I feel bad about making baby feel uncomfortable/cold. Is that silly to feel. Is baby really unhappy when there is a cold intestine pushing against baby's home?
