7 month boy suddenly refuse formula milk and didn't eat as normal he avoid food suddenly??? he usually enjoy and eager to eat all food.

A. Teething could be one reason second could be that you may not be adding salt and spices into the food initially kids like to eat what you give because it’s a break from the milk that you have given but over the period once it’s totally tasteless they do not enjoy so I salt and all the necessary necessary spices required and see if that helps
