I'm sure I'm posting long-past the death of this thread, but I'll add my 2. One thing to think about is that anesthesiologists can do fellowships in pediatric anesthesia alone or combined with pediatric critical care (CHOP, Hopkins are two). The nice thing about the combined fellowship is that you can (depending on the hospital you are at) practice within both fields. Some might also consider it a great advantage to get to the goal of practicing critical care pediatrics without having to go through general pediatrics residency. To some (esp. those who are very subspecialty oriented) learning developmental milestones, doing routine well-baby exams...is tedium at best. There is no way to train in neonatology without doing a peds residency first. Another thing to think about, as a corollary to the above, is what might appeal to you about the neonatology field vs. the peds CCM field (an option from anesthesia, as stated). Some like neonatology for its access to critical patients and procedures, but somewhat more narrow list of diagnoses and pathophysiologies encountered (you know, the old joke that there are only 10 diagnoses in neonatology) and more narrow age-range of patients. Others would consider this a negative and find that the variety of pathology that can be encountered in the PICU the different age ranges (I've helped to care for 2 day old to 17 year olds in our PICU) to be appealing (though you'll see plenty of "bread-and-butter" critical patients [asthma, respiratory failure, sepsis...]). PICU patients can often be chronic boarders, but the plethora of NICU feeder/growers whose eyes need to be checked, whose head ultrasounds need to be redone are painful to some and beloved by others. I am the type that does fine with the acute resussitation of the neonate, but hates the chronic care thereafter (Oh God, RN Ratfarm, please don't show me another residual at 0200...No...No...ARRRGGH!!!). But there are many who have a passion for both (thus, probably the reason it is the only pediatric subspecialty that is not undermanned). I came to residency knowing I wanted to be a pediatric cardiologist but I really enjoy the PICU despite how challenging a field it can be. So evaluate your personality and goals and think about what options are there. Don't just evaluate the positives of either field, but also the negatives that may be avoidable by training in the other (obviously, if you can't stand adults, not going into gas maybe the best...).
