Yes. And child psychologists will tell you that babies and children crave consistency, variety is not their thing. In fact, one of the reasons we as parents (adults) expose them to variety is so they develop an understanding of how to cope with inconsistencies. And it's always a careful balance, small amount of variety but mostly consistency.

And I can tell you most little kids love hard boiled eggs which I suspect is because they are incredibly consistent in texture and taste, unspoiled by some cook seasoning them or cooking them differently.
