Context: He was in a good mood at the doc 's , we saw the happy - hippie doctor that I like so much , and he 's apparently within normal spec for babyhood . She did note the referral to a developmental specialist at his 12-mo appt , and asked if we 'd kept it , and I blithely said no . She looked over his current checklist and was fine with that decision . ( I neglected to tell them that my child - specialist spouse continues to maintain that they 're using the instrument incorrectly .

Question: What may be the reason for the baby being in a good mood at the doctor 's office ?
Options:
0. He wants a treat after the visit .
1. He is excited to get shots .
2. He does n't like the doctor .
