Health & Warning Signs
A calm, clear reference for what a healthy newborn looks like day to day — and the specific signs that mean it's time to call your pediatrician.
Quick answer
Key takeaways
Contact your pediatrician promptly if you notice
As a new parent, one of the hardest parts of the early weeks is figuring out what's normal and what isn't. This guide gives you a general, practical reference — but it doesn't replace your pediatrician, who knows your baby's specific history and can examine them directly. When in doubt, call.
There's a wide range of "normal," but a few consistent markers are useful to watch:
Mild jaundice — a yellowish tinge to the skin and eyes — is common in the first week and often resolves on its own as a newborn's liver matures. It's worth monitoring because it can occasionally need treatment:
Feeding and diaper output are two of the most reliable everyday indicators of how a newborn is doing, because they reflect whether your baby is getting what they need:
Beyond the general picture, a short list of specific signs consistently signals "call your doctor now":
A single unusual moment — one fussy evening, one smaller feed — is rarely a cause for alarm on its own. What matters more is a genuine change from your baby's normal, especially when a few signs show up together (for example, poor feeding and lethargy and fewer wet diapers). You know your baby's day-to-day pattern better than anyone; trust that instinct alongside this list.
Pediatric offices expect and welcome calls from new parents — asking "is this normal?" is one of the most common questions they field, and there's no such thing as a silly question when it comes to your newborn. If something feels wrong, it's always reasonable to call, even if it turns out to be nothing.
