using servo control on a dressed neonate??

Servo shouldn't be used on a dressed neonate. It irritates me when people wrap babies in so many blankets that they are impossible to find in the pile of fabric. Wrapping a baby who is already on the cool side is like trying to melt an ice cube with a blanket. All it ends up doing is insulating a baby AGAINST the warm air in the isolette. Never put more than 2 blankets and a hat on a baby. If he needs more than that to stay warm, you either need to go back up on the temp, or examine whether or not an infection is present. Kids like these end up burning SO many calories to stay warm, just because we want to push them into a crib.

When doing a lit search on a basic topic like this, you often need to go back several years -- not just 3-5. That's because a lot of the research was done years ago (e.g. 1970's? 1980's?). Since it has already been researched and the evidence/rationale is already established, more recent researchers have focused on other things.

Another place to look would be the "practice guidelines" of the various neonatal/pediatric professional organizations. Visit their websites and see what they have. That would give you the national standards for such issues.
