Babies get both thirsty and hungry.
While breast milk and formula provide hydration as well as nutrients, babies can still experience thirst independently of their hunger. The idea that breast milk always sufficiently hydrates a baby isn't always accurate, especially in certain circumstances.
Here's a breakdown:
-
Breast milk and formula: These are designed to meet a baby's nutritional and hydration needs. They contain water, electrolytes, and other essential nutrients.
-
When thirst becomes more prominent:
- Hot weather: Just like adults, babies can become more thirsty in hot weather.
- Increased activity: If a baby is particularly active, they may need more fluids.
- Illness: Conditions like diarrhea or vomiting can lead to dehydration, increasing a baby's thirst.
- Lactose intolerance: The reference mentions that greater faecal loss may indicate a mild lactose intolerance which can also lead to dehydration.
-
How to tell if a baby is thirsty:
- Increased fussiness or irritability, even after feeding.
- Dry mouth.
- Fewer wet diapers than usual.
- Sunken soft spot on the head (fontanelle).
- Dark yellow urine.
-
Addressing thirst:
- Breastfeed or formula-feed on demand.
- Consult a pediatrician about offering small amounts of water to babies older than 6 months, especially in hot weather or if they are showing signs of dehydration. Always consult a doctor before introducing water to babies younger than 6 months.
In summary, while breast milk and formula are designed to provide both nutrition and hydration, babies can still experience thirst, especially under specific circumstances. Recognizing the signs of thirst and addressing them appropriately is important for their well-being.
