So I have this 13 month old that will ONLY eat Cheerios. I serve a WIDE variety of lunches with at least 3 options per meal (all of which I expect to be eaten). However, this child will only eat Cherrios for every meal. Breakfast, snack, lunch, snack. His mom supplies the box of cereal, as I normally do not have specific cereals on hand. But I WANT him to eat what I serve. He is very little to begin with.

Today I tried to serve shredded roast beef with gravy (last nights dinner), roasted potatoes, grape tomatoes and barlett pears. He SCREAMED for about 10 minutes until I poured cheerios onto his highchair and he downed them.

His mom does not seem concerned and openly said that she is fine if he only eats Cherrios all day (5:45am-4:45pm). What should I do? Should I even continue to waste food by serving it to him? Should I take away the Cheerios completely? Should I offer just a small option of the real lunch?

I have done ALL of the above by the way, just not sure which method I should stick with.
