Breasfeeding and supplementing.

So i have a 2 week old baby girl and the first week she wasnt having enough breastmilk. She would latch on both then i would supplement with 2 oz formula. Now that shes getting the hang of breastfeeding it seems like she doesnt want the formula anymore. I dont want to take it away completely because when i pump its not enough to supplement with breastmilk. I dont know what to do. Any suggestions? Anybodys LO doing this?
