My baby is now 8 months old. Started solids after he was 6 months. Initially he was eating a bit of everything but now he has totally stopped taking solids. He closes his mouth tight so can't feed him anything at all. He won't have much of breast milk also. In last couple of months he had ear infection and cold. As a resul he hasn't gained weight since then. I'm worried about his eating habits. I have tired to feed him cerelac, booked vegetables, furits, homemade purees, etc. He doesn't likes anything. Please advice
