Is it better to have an older or younger pediatrician?
I would pick an older pediatrician, hands down...you get the wisdom they've earned over the years and the experiences they've incorporated into their intuition and their medical style.
I had a scary ER experience that made me stress for months. I now fly to Portugal once a year for routine check-ups.
The experience in the US ER left me questioning the medical system after being suggested I had cancer without concrete proof, highlighting the drastic differences in costs.
