my baby is not drinking formula milk or breastmilk he is eight months old what should I gave him to eat

A. Hello good evening !! As the baby is 8 months old give semi solids - Cerelac ,dal kichdi or dal rice,curd rice,porridge,fruit and vegetable purie/mash after checking the suitability . During teething babies have gum pain so they reject feeding,give teethers/soothers ,finger foods ,breast feed which helps in easing gum pain .
