Normal vs. Concerning
By Age
What to expect by age
0-3 months
Young babies do not typically drink bath water intentionally. If baby swallows a small amount during bathing, it is not concerning. Use lukewarm water and minimal bath products.
4-6 months
Babies begin splashing and may get water in their mouth. This is normal and a small amount is harmless. Keep bath products gentle and fragrance-free.
6-9 months
Babies become more playful in the bath and may intentionally put their mouth to the water. Redirect with splash toys. Avoid adding soap until the end of the bath to minimize what baby ingests.
9-12 months
Bath water drinking becomes more intentional as baby explores. Offer a cup of clean water to drink instead. Keep the bath water as clean as possible and change it if it gets very soapy or dirty.
12-24 months
Toddlers may drink bath water deliberately. Give them a cup of fresh water at bath time to satisfy their thirst. Teach them that bath water is not for drinking. Small amounts remain generally harmless.
What to Tell Your Pediatrician
- Describe when you first noticed keeps drinking bath water and how it has changed over time.

- Mention if bath products used are strong or not intended for babies.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.

Related Conditions
My Baby Eats Non-Food Items (Pica)
It is completely normal for babies and young toddlers to explore by putting objects in their mouths. True pica, which is the persistent eating of non-food substances, is uncommon before age two and may be linked to iron deficiency or developmental factors. If your child repeatedly seeks out and eats non-food items past the typical mouthing stage, it is worth discussing with your pediatrician.
My Baby Keeps Eating Dirt and Sand
Babies and toddlers explore the world by putting everything in their mouths, including dirt and sand. Small tastes are very common and usually not harmful. However, soil can contain parasites, bacteria, pesticides, or lead, so it should be discouraged. If your child repeatedly seeks out and eats large amounts of dirt, this could be pica, which may indicate a nutritional deficiency like iron.
When Can Babies Drink Water Safely
Babies under 6 months should NOT be given water. Breast milk or formula provides all the hydration they need, even in hot weather. Giving water to a young baby can cause water intoxication, a dangerous condition where sodium levels drop to dangerous levels, potentially causing seizures. After 6 months, when solids begin, small sips of water (2-4 oz per day) can be offered in a cup. By 12 months, water becomes a regular part of the diet alongside whole milk.

When to Introduce Allergens to Baby
Current guidelines recommend introducing common allergens (peanut, egg, cow's milk products, tree nuts, wheat, soy, fish, shellfish, sesame) starting around 4-6 months when your baby is developmentally ready for solids. The landmark LEAP study showed that early introduction of peanuts (by 4-6 months) reduced peanut allergy risk by 80% in high-risk infants. Do not delay allergens - the old advice to wait until 1-3 years has been reversed because early exposure actually prevents allergies.
I'm Worried My Baby Is Aspirating During Feeds
Aspiration means liquid or food enters the airway instead of the stomach. Occasional coughing during feeds is common and does not usually indicate aspiration. True aspiration is less common and may present as recurrent respiratory infections, a wet or gurgly voice after feeds, or chronic cough. If you are concerned, a swallow study can provide a definitive answer.
When Does My Baby Need Amino Acid Formula?
Amino acid-based formulas (also called elemental formulas) are prescribed for babies with severe cow's milk protein allergy, multiple food protein intolerances, or conditions like eosinophilic esophagitis who cannot tolerate standard or extensively hydrolyzed formulas. They are the most hypoallergenic formula available because the proteins are broken down into individual amino acids, making allergic reactions virtually impossible.
