I don't have a 3 yo, but what if you just went along with the train of thought for a while.. and asked What kind of iceblock? Can you draw me a picture of the iceblock? Where could we buy one from do you think? Maybe when we go for a walk..

Then try and redirect back to breakfast? I am not sure if it would work, but it sounds like she wants hr voice to be heard.

I may be way off so I hope someone else replies soon!
