I have proof that a toddler can have a tantrum over just about anything.
Daddy decided to give Billy chocolate milk with dinner instead of plain milk.
"I don't want it!" he screamed.
We tried to convince him that he would like it but the more we tried to convince him the more he screamed. Eventually, we just tried to calm him down so he would eat rather than scream. He had epic meltdown over the milk.
But then, randomly, he tried it.
Wait! What's this? Chocolate milk tastes... wait for it... good??? Why didn't someone tell me this tasted good? Can I have more?
Yes, it's true. Chocolate milk does taste good. Oh, and Billy likes it now. Yep. When I gave him regular milk he handed it back, "Mommy, yucky. Chocolate?"
Proof that toddlers will throw a tantrum over even the good stuff.
