Context: I picked Peanut up from school on Tuesday . It was her first day or preschool- that girl has had a good number of changes ( bunk bed , sharing rooms , baby , starting school , etc . ) in the last month and I have to say that I think she 's really coming into her own , it seems to be helping her mature ( again , knocks on wood ) . Anyway , I was the last one to pick my kid up ( really , I used to be punctual , even EARLY , before I had kids ! )
Question: What age group is peanut a member of ?
Options: 
- None of the above choices .
 - She is a young child .
 - She is a big kid .
 - She is a small baby .


She is a young child .
