我不是小Baby

Last time I was kidding Keke that she is like a little baby.  Keke became mad, complained to her Mom again and again “我不是小Baby ”.  Then I said to her, “你是个大Baby.”  Keke became even madder.  I heard these kids always yelled at each other at daycare, “你是个Baby”.  That’s the very thing they really hate to be called.
