I hear it a lot from parents of my toddler patients.
“He used to be such a ‘good eater’!” Meaning, their little one used to polish off all of the healthy things they put in front of him. Broccoli, apples, peas, fish, sweet potatoes, tomatoes, etc.
Their little baby with the cute toothy grin was eating the rainbow! They were rocking it as parents, but then one day it happens and the party is over.
