Baby only wants to eat at night? Or...

SH
I was wondering when your baby wakes at night do you automatically assume he's hungry and just feed him? Or do you try to see if he just wants something else like to be cuddled or something? I'm talking about infants like under 3 months. My 6 week old obviously wakes at night and I just feed him...but do babies that age wake for anything else possibly? Or they only wake up to eat?
