breastfeed

Can i consider myself at baby ko na pure breastfeed or applicable lang yung ebf since day 1 ni baby na di nakatikim ng formula? Curious lang ako. Mixfeed kami ni baby hanggang 1 minth kasi inubos ko yung formula..sayang din bago nag exclusive breastmilk. Macoconsider na ba kaming pure bf? 3 months na.siya btw ?
