Your newborn baby is going through many changes in getting used to life in the outside world. Almost always this adjustment goes well, however there are certain warning signs you should watch for. Some general warning signs with newborns include:
Not urinating (It may be hard to tell, especially with disposable diapers)
No bowel movement for 48 hours
A rectal temperature over 100.4° F (38° C) or less than 97.5° F (36.5° C)
Breathing fast (for example, over 60 breaths per minute) Or a bluish skin coloring that does not go away. Newborns normally have irregular respirations, so you need to count for a full minute. There should be no pauses longer than about ten seconds between breaths.
Retractions, or pulling in of the ribs when taking a breath
Wheezing, grunting, or whistling sounds while breathing
Odor, drainage, or bleeding from the umbilical cord
Worsening jaundice or yellowing of the skin on the chest, arms, or legs, or whites of the eyes
Crying or irritability which does not improve with cuddling and comfort
A sleepy baby who cannot be awakened enough to nurse or bottle feed
Signs of sickness (for example, cough, diarrhea, pale skin color)
Poor appetite or weak sucking ability
Every child is different, so trust your knowledge of your child and call your child's doctor if you see signs that are worrisome to you.
