Mixed Feeding??

Hello po. si baby boy ko po is 5 months old weighing 7.1 kls. pure breastfeed po. normal po ba yung weight niya? advised po kasi ni pedia na mag-ayuda (enfamil) to gain weight. parang ayaw ko po kasi baka hindi mahiyangan ni baby. baka magsuffer pa yung health niya. Thanks po #AskingAsAMom #Needadvice
