4 months old can eat already?

My baby also start solid food(Cerelac, the rice flavor, once a day, mixed with breast milk) at 4 months old. Paediatrician advice that my baby ready for solid food after she saw my baby growth development. Maybe you should get advice from Paeditrician instead of general doctor since they’re more expert and specializing with baby. WHO did mentioned that we can start introducing solid food between 4 to 6 months old but after consult with paediatrician. Again, all babies not the same. I really encourage you to consult with Pediatrician.
