Hi Alida.
I do take my daughter for the yearly check up, she went at 1 and at 2 years old, also a healthy child,so we only see the pediatrician at the yearly check up and the GP when we have the old cold etc.
Our Dr is very good, she is thorough at the yearly check up, she does a developmental assessment and then a physical exam, the developmental assessment is really just a 15 - 20 minute discussion/ questionnaire around Paige's development, so last time we spoke around talking, potty training, coordination, ability to screw jar caps, build with building blocks, etc- we also chatted about food, eating and sleeping etc
Then she did a 10-15 minute physical exam, this was thorough, ie check heart, kidneys, stomach, ears, throat etc. they only do blood tests if there is something wrong, so for me that wasn't something I expected. If your child is healthy, I doubt they will send you for any blood work as this would only be the cause if they suspected something was wrong
in total , our appointment was probably about half an hour - 45 minutes.
