Casey is 2 years and half and she is a "terrible two" baby, feisty and independent-minded.
It is a challenge raising a two-year old very independent-minded, very confident baby who knows exactly what she wants.
Wikipedia's descriptions of a terrible two kid perfectly fit Casey to a tee:
Casey is often defiant; shouting "no" to everything she doesn't approve of.
She is very bossy, demanding from everyone and expects immediate attention by crying. Casey is very clever in using crying to get the attention she wants.
Casey is very impatient.
