what to do if 7 month old rejecting food?

A. Hai good evening !! Check texture as you have started semi solid foods recently change in texture liquid to semi solid might be one reason. Another one is teething ,due to hard swollen gums they will be cranky reject feed . Check if baby having hard ,reddish,swollen gums motions,fever ,gum pain then soothe with teethers to ease from gum pains,give semi solid foods.
