My son is 9 months yesterday he had being refusing food a little still eating some stuff but today he is just not having any of it I do baby led but also feed him stuff like porridge cereal and yogurts but he won't let me spoon feed him just spits it out if I manage to get the food in and when I give him the food he will just play with it for a second or two then throw it this isn't like him at all he loves his food he's sort of having bottles it's taking him an hour to finish it but he does keep going back to it he has 3 a day should I offer him an extra one cause of lack of food?

He's sleeping more than usual too I don't know if this is teething or if he's getting croup my sister currently has it
