Feeding schedule

My babygirl will be two months in a week. She is still feeding every two hours on cue! She drinks 3&1/2 ounces of enfamil gentlease. How can I get her to go longer between feedings? Or is this completely normal and when should she start doing this on her own? When I bathe her she has slept 4 hours before( I usually do this in afternoon so it's really no help for night time) and one random night she gave me 5 hours before feeding.
