Baby eats every 1 1/2-2 hours

My daughter is 2 months old and she eats every 1 1/2-2 hours. I feel like all I do is nurse. I know I have enough breast milk because when I pump I can get anywhere form 2-4 oz at a time. She's wetting diapers just fine and she's gaining weight. Anyone else's LO do this!? I'm going back to work In about two weeks and will be breast feeding at lunch time in the mornings before work, after work, and throughout the night if needed. She will get a bottle throughout the day. I'm hoping maybe she will space out her feedings once were separated for some hours.
