Quick Answer
AAP guidance says to call your doctor or seek care now when a baby has trouble breathing, bluish lips, nonstop coughing, wheezing, or looks very sick. For infants under 12 weeks with fever, contact your clinician before giving fever medicine. Call 911 for severe trouble breathing or stopped breathing.
What Parents Need to Know
Coughing is common in babies and often comes with colds. Most coughs improve with time, fluids, and rest.
Young infants are different. A cough that seems mild in an older child can signal a serious illness in a newborn. When in doubt, call your clinician.
Evidence-Based Guidance
AAP cough guidance for infants 0-12 months explains:
- Call 911 for severe trouble breathing, stopped breathing, or bluish lips when not coughing
- Seek care now for trouble breathing, wheezing, or fast breathing
- Nonstop coughing spells and bluish lips during coughing need prompt evaluation
- Fever in babies under 12 weeks requires clinician contact before fever medicine
- Dehydration signs—fewer wet diapers, very dry mouth—warrant urgent attention
- Contact your doctor if cough lasts more than three weeks
AAP children and colds guidance adds:
- Call at the first sign of illness in infants three months or younger
- Seek care for nostrils flaring, ribs pulling in, or fast breathing
- Bluish lips or nails need immediate attention
- Nasal congestion lasting more than 10-14 days may need evaluation
- Ear pain or persistent fussiness alongside cough should be checked
- Most older infants improve within about one week, but watch closely
CDC RSV guidance describes:
- Cough, runny nose, and decreased appetite as common symptoms
- RSV can cause breathing difficulty especially in infants
- Wheezing and rapid breathing are warning signs
- Premature infants and very young babies are at higher risk
- Contact your clinician when breathing or feeding changes concern you
Health Canada RSV guidance notes:
- RSV is a common respiratory virus in infants and young children
- It can cause serious breathing problems in some babies
- Monitor breathing, feeding, and hydration during illness
- Seek care when symptoms worsen or your baby looks very ill
- Prevention includes hand washing and limiting exposure when possible
Practical Steps
- Monitor breathing—count breaths per minute if your baby seems fast or labored.
- Suction nasal mucus gently with saline drops if congestion affects feeding.
- Offer frequent feeds to maintain hydration.
- Keep your baby upright for sleep in your arms if very congested—but return to a safe sleep surface for naps and night sleep.
- Note fever and contact your clinician before medicine in infants under 12 weeks.
- Wash hands and limit sick-contact exposure.
- Call early rather than waiting overnight with breathing concerns.
