Intro to solid foods

Good morning, Hi po, my baby boy turned 6 mos. last April, so I started introducing him to foods like steamed veggies with breastmilk. Pero everytime na papakainin ko siya naisusuka niya po yung kinain niya pati yung nadede niyang milk from me. Is it normal po? Ano po kaya ang puwede kong gawin? Thanks in advance po ?
