Solids over milk???

My son is just over 8 months old and most meal times he doesn’t want his milk. He gets a bottle of breastmilk or formula. I’m not sure if it’s a teething thing or what. I know milk or formula is still suppose to be their main source of food but what if he won’t drink it?!! Ugh 😑
