Feeding Schedules?

My LO will be 2 months tomorrow and I want to try and get him into a better feeding schedule - he's formula fed! So far he just eats little bits here and there all day, and will kind of do the same at night, which only gives me a two or three hour sleep stretch at a time. How do I go about starting a more set schedule to help him sleep more at night?
