Yes, an 8-month-old can drink water, but it should be in moderation and must never replace breast milk or formula.
Understanding Infant Hydration Needs
Infants have unique hydration needs that differ significantly from those of older children and adults. During the first six months of life, babies receive all the hydration they need from breast milk or formula. These liquids provide not only hydration but also essential nutrients for growth and development. As babies approach the 8-month mark, parents often wonder about introducing water into their diets.
At this stage, babies are typically starting solid foods, which can lead to questions about hydration. It’s crucial to understand that while water can be introduced, it should complement rather than replace the primary sources of nutrition. The American Academy of Pediatrics advises that small amounts of water can be given to infants as they start consuming solids.
| Age Range | Total Daily Fluid Need* (all sources) | Suggested Plain-Water Portion |
|---|---|---|
| 0 – 6 months | ≈ 700 mL (exclusively milk) | 0 mL — milk only |
| 6 – 8 months | ≈ 800 mL | Up to 60 mL (2 oz) offered with solids |
| 8 – 12 months | ≈ 900 mL | Up to 120 mL (4 oz) spread over meals |
| 12 – 24 months | ≈ 1 000 mL | 240 – 720 mL (1 – 3 cups) per thirst |

The Role of Breast Milk and Formula
Breast milk and formula are designed to meet all of a baby’s nutritional needs for the first year of life. They contain the right balance of proteins, fats, vitamins, and minerals necessary for healthy growth. Here’s a closer look at why these liquids are so vital:
Nutritional Composition
| Nutrient | Breast Milk (per 100 mL) | Infant Formula (per 100 mL) |
|---|---|---|
| Calories | 70 kcal | 67 kcal |
| Protein | 1.0 g | 1.3 g |
| Fat | 4.0 g | 3.6 g |
| Carbohydrates | 7.0 g | 7.0 g |
| Calcium | 30 mg | 50 mg |
| Irritable Bowel Syndrome (IBS) | – | – |
As illustrated in the table above, both breast milk and infant formula provide essential nutrients needed for development during the early months.
The Right Time to Introduce Water
Around six months, most babies start eating solid foods, which can lead to questions about hydration needs. By eight months, introducing small amounts of water is generally considered safe and beneficial.
However, it’s essential to do this gradually:
- Start Small: Begin with just a few sips during meals.
- Monitor Reactions: Observe how your baby responds to water.
- Avoid Overhydration: Too much water can lead to a rare but serious condition called water intoxication.
Signs Your Baby Might Need Water
As your baby begins solids and becomes more active, you might notice signs indicating they could use some extra hydration:
- Dry Mouth: If your baby’s mouth seems dry or sticky.
- Decreased Urination: Fewer wet diapers than usual.
- Increased Thirst: If they appear unusually thirsty after eating solids.
These signs suggest your baby may benefit from small amounts of water alongside their regular feedings.
Keeping Baby Hydrated When Life Gets Messy
Fever, Vomiting or Diarrhoea
Illness steals fluids fast. Offer more frequent breastfeeds or bottles first; then tiny water sips (10–15 mL) every 20 minutes for babies over six months. Oral rehydration salts (ORS) beat plain water if stools are watery or vomiting persists more than eight hours—mix exactly as directed. Call your paediatrician if urine stays scant (fewer than four wet diapers in 24 hours) or the fontanelle becomes markedly sunken.
Hot Weather & Travel Days
Dress baby in light cotton, shade the stroller, and schedule outdoor play before 10 a.m. or after 4 p.m. For babies over six months, pack a pre-measured straw cup (60 mL) and offer it at each rest stop or before boarding a flight. Plan an extra breastfeed or bottle during take-off and landing to ease ear pressure and top up fluids.
The Best Practices for Offering Water to Your Baby
Selecting the Right Type of Water
Most city tap water in high-income countries is closely monitored and usually fluoridated. Run the cold tap for 15–20 seconds, then fill your baby’s cup or kettle. If your home has old lead pipes or your water-quality report shows lead or nitrate above safe limits, use an NSF-53 certified filter or bottled water labelled “purified,” “distilled,” or “demineralised.” Boiling kills germs but does not remove lead or nitrates, so filtration is key. When in doubt, contact your local water authority for the latest test results.
Fluoride Facts Without the Fear
Fluoride strengthens enamel long before teeth erupt. The optimal level is about 0.7 ppm. Formula prepared with fluoridated tap water remains safe, but exclusive formula feeding for many months can cause mild dental fluorosis. If you’re concerned, alternate between tap water and low-fluoride bottled options. Never add fluoride drops or tablets unless prescribed.
Quick Quality Check
Request the latest utility report for nitrate (under 10 mg/L) and lead (under 15 ppb). In older homes, a countertop filter certified for NSF-53 (lead) and NSF-42 (particulates) removes most contaminants. Replace cartridges on schedule—over-used filters can harbour bacteria.
Pacing the Introduction of Water
Start with offering just a few sips at mealtime using a sippy cup or a spoon:
- Use a Sippy Cup: This helps develop motor skills while making drinking easier.
- Limit Amounts: Offer no more than an ounce or two at first.
- Timing Matters: Offer water during meals rather than between feedings so it doesn’t interfere with their appetite for breast milk or formula.
From Bottle to Open Cup—Why It Matters
Open and straw cups encourage proper lip closure and tongue movement, setting up better dental health down the road. Begin with silicone-rimmed trainer cups and pour in just enough to coat the bottom so spills are tiny. Increase volume as coordination improves.
On-the-Go Toolkit
- Collapsible silicone cup plus screw-top water pouch keep the diaper bag light.
- Clip-on cup strap stops the “drop game” at restaurants.
- At night, place a tiny cup of cooled, boiled water on the dresser (for trained sippers older than eight months) so midnight thirst doesn’t derail sleep.
Parents who make water a low-pressure habit—offered, never forced—raise kids who instinctively reach for clear liquids. Your eight-month-old is already on that path.
The Risks of Overhydration in Infants
Understanding Water Intoxication
Water intoxication occurs when an infant consumes excessive amounts of water relative to body weight:
- Symptoms: Irritability, drowsiness, nausea, vomiting, and—in severe cases—seizures.
- Prevention: Always monitor how much water your baby consumes and ensure it remains within safe limits.
It’s crucial for parents to strike a balance between ensuring adequate hydration without overwhelming their young digestive systems with too much liquid.
The Impact on Breastfeeding and Formula Feeding
Nutritional Priorities Remain Key
Breast milk or formula should remain the primary source of nutrition up until one year old:
- Hydration from Milk: Both options provide sufficient hydration on their own.
- Gradual Transition: As you introduce more solids into their diet alongside small amounts of water, continue prioritizing breast milk or formula.
Cultural Practices Around Infant Hydration
Cultural norms influence how parents approach infant feeding practices worldwide. In some cultures, it’s common to offer herbal teas or diluted juices even before six months. However, pediatricians generally recommend sticking with breast milk or formula until about six months before introducing any other liquids. Understanding these cultural nuances helps parents navigate choices while ensuring they align with health recommendations.
The Role of Solid Foods in Hydration Needs
Certain solid foods contribute significantly to hydration levels:
- Fruits & Vegetables: Options like watermelon and cucumber contain high moisture content and can support overall hydration.
Incorporating these foods into your baby’s diet keeps them hydrated while also providing essential nutrients.
The Importance of Monitoring Fluid Intake in Infants
Parents should always track how much fluid their child consumes daily to ensure they are meeting both hydration and nutritional requirements.
Dairy Considerations After One Year Old
After your baby’s first birthday you can add whole cow’s milk (max 16–24 oz a day) for calcium, fat, and protein, but water should remain the main thirst-quencher. This transition allows parents flexibility while continuing to ensure proper nutrition throughout early childhood.
