I agree!!!
She looks to be a 4 year old (at most) little girl...
What 3-4 year old little girl would even be able to read the fine print labels and understand those words.
It is not even within the realm of 'believeable' or 'reality'.
IMHO, anybody who automatically jumps to calling a little adorable 3-4 year old girl (who is just making a commercial) names like smart aleck little brat who should be physically smacked, must have some real issues.
