There is a particular kind of 2am uncertainty that almost every new parent knows: something feels off with your baby, but you cannot name it precisely enough to feel justified calling anyone. You wonder if you are overreacting, whether the health visitor will think you are anxious, whether the thing you are worried about is just normal newborn behaviour wearing an unfamiliar face. This guide is designed to make that uncertainty more navigable. It is not a medical checklist — it is a calm, practical framework for recognising when professional input will genuinely help, and what those situations actually look like. Asking for help with newborn care is not a sign of inexperience. It is exactly what the healthcare system is there for.

The Principle Behind This Guide: When In Doubt, Reach Out

Before any specific sign or symptom, the most important thing to internalise is this: there is no call to a midwife, health visitor, or GP that is a wasted call when a newborn is involved. Healthcare professionals who work with families in the postnatal period expect questions, they are not annoyed by them, and the cost of an unnecessary call is zero. The cost of a delayed call when something genuinely needs attention can be significant. If something about your baby is worrying you and you cannot find a clear reason why it should not be, that instinct is worth acting on. You know your baby. You are the person best positioned to notice when something has shifted.

With that foundation in place, here is a practical guide to the specific areas new parents most commonly need help navigating.

Feeding Concerns: When to Seek Support

Feeding difficulties are the most common reason new parents contact their midwife or health visitor in the first weeks — and the most common area where waiting too long to reach for support creates unnecessary difficulty. The specific situations that warrant professional input include: a breastfed baby who has not regained their birth weight by two weeks, or whose weight is dropping after initial regain; a baby who is consistently producing fewer than six soaking wet nappies in 24 hours after day five; a breastfeeding parent experiencing persistent nipple pain beyond the first few days of latch adjustment; or a baby who is very sleepy at every feed and difficult to keep awake long enough to take adequate milk. Early feeding support — from a lactation consultant, specialist midwife, or health visitor trained in infant feeding — is far more effective than late support. Do not wait until you are at crisis point.

Formula feeding concerns worth raising

If you are formula feeding and your baby seems consistently unsettled after every feed, is vomiting significantly more than small posseting, has developed a rash in the weeks since starting formula, or is not gaining weight appropriately, these are patterns worth discussing with your GP rather than switching formulas independently. Formula intolerance and allergy are less common than they are perceived to be, and a structured medical assessment is more useful than a series of formula changes that may not address the actual cause.

Sleepiness: The Sign Most Often Missed

Most parents worry about a baby who does not sleep enough. Fewer think to worry about a baby who sleeps too much — but in the newborn period, excessive sleepiness is one of the most important signs to take seriously. A newborn who is very difficult to rouse for feeds, who seems limp or floppy when awake, who has a noticeably weak cry, or who is spending significantly more time asleep than awake and cannot be roused to feed every two to three hours needs to be assessed by a health professional promptly. Excessive sleepiness in newborns can be associated with jaundice, infection, or inadequate feeding — all of which are manageable when identified early. If your baby is not waking to signal hunger and is difficult to rouse, contact your midwife the same day rather than waiting for a scheduled visit.

Crying: Knowing When It Is More Than Colic

Prolonged crying in an otherwise healthy newborn is most commonly colic — exhausting and distressing, but not medically serious. However, there are specific crying patterns that warrant professional assessment rather than home management. Contact your GP or call NHS 111 if your newborn’s cry is high-pitched or sounds distinctly different from their usual cry; if crying is accompanied by a fever (38°C or above in a baby under three months); if the baby is inconsolable and not responding at all to feeding, nappy changes, or soothing over several hours; if crying is accompanied by visible signs of pain between episodes — arching the back, drawing up the legs — that persist rather than resolving; or if a baby who previously cried predictably in the evenings suddenly begins crying differently or at different times. Trust the difference. You have been listening to this baby. You know when something has changed.

Temperature: The Numbers That Matter for Newborns

Fever in newborns is treated with considerably more urgency than fever in older children because a young baby’s immune system is still developing and infections can progress rapidly. The guidance is clear and worth memorising: any temperature of 38°C or above in a baby under three months requires same-day medical assessment, regardless of how well the baby appears otherwise. Do not wait to see if it comes down. Do not give paracetamol and see how they go. Call your GP or go to your local emergency department — both are appropriate responses. For babies over three months, a temperature of 39°C or above warrants the same same-day response. Use a digital axillary (underarm) thermometer — it is the most accurate method for young babies.

Jaundice: What to Watch For

Newborn jaundice — yellowing of the skin and whites of the eyes — is common in the first week and often resolves without treatment as the baby feeds and the bilirubin clears. However, jaundice that appears in the first 24 hours after birth (before the usual physiological jaundice window), jaundice that is severe (very deep yellow, spreading to the arms and legs), or jaundice that persists beyond two weeks all require medical assessment. Your midwife will check for jaundice at routine postnatal visits, but you are with your baby between those visits. In natural daylight, check the skin on the chest and the whites of the eyes — yellowing that seems to be spreading or deepening is worth raising promptly rather than waiting for the next scheduled visit.

“”New parents often apologise for calling. They say, ‘I know it’s probably nothing.’ The truth is, knowing when it’s something — and having the confidence to reach out when you’re not sure — is one of the most important skills of the newborn period. We would always rather hear from you.””

— Dr. Philippa James, GP and columnist for Practical Parenting magazine. Dr. James specialises in postnatal parent support and consistently advocates for reducing the barrier to contact that many new parents experience — the hesitation that comes from not wanting to seem anxious or inexperienced. Her perspective directly underpins the approach in this guide.

Frequently Asked Questions

Should I call the midwife or go straight to A&E with a newborn concern?

For non-urgent concerns — feeding worries, mild jaundice, questions about normal behaviour — your community midwife, health visitor, or GP is the right first contact. For urgent concerns — difficulty breathing, a high-pitched or unusual cry, a non-blanching rash, a temperature over 38°C in a baby under three months, or a baby who is unresponsive or difficult to rouse — go to your nearest emergency department or call 999 without delay. When you are unsure which category your concern falls into, calling NHS 111 first is a good option: they can triage and advise on the most appropriate next step based on what you describe.

My baby passed the meconium stage but has barely had any dirty nappies — is this a problem?

Stool frequency in babies varies considerably and changes with age and feeding type. Breastfed babies in particular can go from pooing after every feed to producing only one stool every few days as they grow — provided the stool is soft, this wide range is normal. In the first two weeks, however, stool frequency is a key indicator of adequate feeding, and fewer than one to two stools per day in the first week is worth mentioning to your midwife. If a baby of any age has not had a bowel movement for more than 48 hours and seems uncomfortable, hard-bellied, or is not feeding well, that also warrants a conversation with your GP or health visitor.

How do I take my newborn’s temperature accurately?

Use a digital thermometer in the armpit — this is the recommended method for babies under five years. Place the thermometer in the centre of the armpit with the arm held gently against the body, and leave it for the full time indicated in the instructions (typically around one minute for digital thermometers). Ear thermometers can be used but are less reliable in very young babies due to the small ear canal size. Forehead strip thermometers are not accurate enough for medical decision-making. If your reading is above 38°C in a baby under three months, seek same-day medical assessment regardless of how well the baby otherwise appears.

My newborn has yellow eyes and skin — when does jaundice need treatment?

Physiological jaundice — the normal newborn jaundice that appears around day two to three and peaks at day four to five — typically resolves without treatment by two weeks in full-term babies. Treatment (usually phototherapy, or light therapy) is recommended when bilirubin levels are above a certain threshold, which your midwife or GP assesses based on the baby’s age and clinical appearance. The situations that require prompt assessment — rather than watchful waiting — are: jaundice appearing in the first 24 hours, jaundice that looks severe or is spreading to the limbs, a baby with jaundice who is feeding poorly or very sleepy, or jaundice that persists beyond two weeks in a full-term baby.

I feel embarrassed calling the health visitor with questions — is that normal?

Completely normal, and also something worth gently pushing past. Many new parents describe hesitating to contact their care team because they worry about seeming anxious, wasting time, or being judged for not knowing something. In practice, postnatal health professionals expect these calls — they are the purpose of the service, not an inconvenience to it. If you find it easier to frame questions as “”I just wanted to check”” rather than presenting them as urgent concerns, that is absolutely fine. The conversation itself is what matters.

Key Takeaways

• There is no wasted call when a newborn is involved — if something feels off, reaching out to your midwife, health visitor, or GP is always the right move.
• Feeding concerns — poor weight gain, fewer than six wet nappies after day five, persistent pain with breastfeeding — warrant early professional input rather than waiting.
• Excessive sleepiness in a newborn is a more significant concern than most parents realise — a baby who cannot be roused for feeds needs same-day assessment.
• Any temperature of 38°C or above in a baby under three months requires same-day medical review, regardless of how well they appear.
• Jaundice appearing in the first 24 hours, looking severe, or persisting beyond two weeks in a full-term baby requires medical assessment rather than watchful waiting.
• Trust your instinct — you are the person most familiar with your individual baby, and changes you notice have clinical value.

New parents carry an enormous responsibility and very little prior experience — that combination makes the threshold for reaching out feel higher than it should be. The health professionals in your postnatal care network are there precisely because newborn care involves questions that benefit from expert input. Use them freely, use them early, and do not wait until worry has become distress before making the call. You are not bothering anyone. You are doing exactly what good parents do.
