Picky Eater baby

Hello mommies. Can you give me some tips on how to make a picky eater baby eat? My daughter is turning 1 and hindi siya masyado kumakain lalo na kapag nasa high chair siya. Kapag binebelt'an ko, nagagalit and gusto niya mag upo tayo siya. Kahit anong gawin ko ayaw niya iopen yung mouth niya. What to do? :(
