What is the longest a baby should go without peeing?

A baby in the lactational stage should generally not go more than half a day (approximately 12 hours) without peeing, as this can be a sign of concern.

Normal Urination Frequency in Babies

For most babies, especially those who are well-hydrated, peeing every 3 to 4 hours is considered normal and healthy. It's common for a baby's diaper to not always feel heavily wet, but as long as urination is consistent within this timeframe, there is typically no cause for concern. The frequency of wet diapers is a key indicator of a baby's hydration and overall well-being.

When to Be Concerned About Infrequent Urination

While occasional variations can occur, a significant red flag is if your baby, particularly one who is primarily milk-fed, does not pee for more than half a day. This prolonged absence of urination is a strong indicator of potential issues, most commonly dehydration.

Signs of Dehydration in Babies

If your baby isn't peeing regularly, it's crucial to look for other signs of dehydration. These can include:

• Dry mouth and tongue: A baby's mouth should normally be moist.
• No tears when crying: A lack of tears can indicate severe dehydration.
• Sunken soft spot (fontanelle) on the head: This is a serious sign.
• Fewer wet diapers than usual: Beyond the half-day mark, even slight reductions can be concerning.
• Lethargy or decreased activity: Your baby may seem unusually tired or less responsive.
• Cool, discolored hands or feet: This can indicate poor circulation due to dehydration.
• Sunken eyes: Another sign of fluid loss.

What to Do If Your Baby Isn't Peeing Enough

If you notice your baby has gone for more than half a day without peeing, or if you observe any other signs of dehydration, it's important to act promptly:

1. Offer more fluids:
   • For breastfed babies, offer the breast more frequently.
   • For formula-fed babies, offer more formula. Do not dilute formula or give plain water to infants unless advised by a doctor.
2. Monitor closely: Continue to observe your baby for wet diapers and other symptoms of dehydration.
3. Seek medical attention: If your baby still isn't peeing after increasing fluid intake, or if they show severe signs of dehydration, contact your pediatrician immediately or seek emergency medical care. Dehydration can quickly become serious in infants.
