Good evening moms and docs. My baby of 4 months has refused suckling anything called feeding bottles. My milk supply after giving birth to him was poor so that's why we added formula. Now he won't even feed on his formula anymore but my breast is hearing it. My son can suck from morning till night, so I don't know if he is getting enough breast milk. He weighed 6.8kg last 2 weeks on his 16weeks appointment. I just want to know why each time he sees his feeding bottle he will start crying and reject the formula. Please I need answers and thanks in anticipation.
