If its every two hours... it could very well be a sleep association too. My LO does that too... for a couple weeks wakes a lot... then only a couple times at night... then will do it more again. Its totally a mixture of things for him. Sometimes teething, illness, growth spurt... all these increase eatings which then get him used to nursing more and then he gets used to it (aka sleep association). I wouldn’t stress over it. Baby’s cant overeat nursing. Increasing daytime food isn’t a bad idea... but if its an association you may want to try sleep training to give yourself a break.
