How fast should a newborn breath, my daughter seems to be breathing fast esp when sleeping and pulling to breath born w fluid in lungs (resolved) she's 1week?

Periodic breathing: Newborns breath fast...Around 40-50 x a minute. They also have a cycle of breathing called periodic breathing where they breathe very fast then slow it down and can have an interval of up to 10-15 seconds of "holding their breath" then it starts over. As long as she is pink and eating well and in no distress she is fine. If worried at all see your pediatrician..Reassurance is very helpful.
