Why or what is stopping my baby from eating?

uh. he doesnt need food at 7 months. babies dont actually need food until closer to a year. have you tried putting real food (what you eat) on his tray and let him explore with it and try to feed himself? my daughter never got spoon fed, just started feeding herself solids at 6 months. you dont need teeth to chew. try fresh fruit, bread, cheese, etc
