A. Hai good evening !! Check if baby is on teething ,while teething babies have hard,swollen gums cause pain ,so they cranky and rejects feed mostly. Soothe with soothers,teethers which ease from gum pain. Give finger foods(Veggies chopped into wedges,finger shaped boiled or steamed ) ,semi solid foods,soups these also ease from gum pain.
