When can babies have watermelon?
Can babies have watermelon?
Babies can have watermelon from about 6 months, as soon as they show signs they are ready for solids. Ripe watermelon is juicy and soft: start with it mashed into yogurt or oatmeal on a spoon, then offer large seedless rectangles to gnaw from 7–8 months and small pieces from about 9 months.
How to serve watermelon by age
Shapes and textures change as your baby’s grasp and chewing grow.
6 months
Remove every seed from ripe watermelon, then mash or blend the flesh and stir it into plain yogurt, oatmeal or iron-fortified cereal so it is thick enough to stay on a spoon. Offer it on a spoon or a preloaded spoon.
7–8 months
Offer a seedless rectangle of ripe watermelon about two adult fingers wide and as long as your hand, so baby can grip it in a fist and gnaw the top, since ripe watermelon squashes easily. You can leave a strip of rind on the bottom as a handle, as long as baby is only sucking and gnawing, not biting the rind.
9–12 months
As the pincer grasp develops, cut seedless watermelon into small cubes about the size of a chickpea, or offer thin slices that break apart easily. Very small, wet pieces can be slippery, so start with a few at a time and let baby practice.
12 months +
Serve bite-size pieces, thin wedges or watermelon mixed into a fruit salad with other soft fruits. Toddlers can start biting from a wedge with the rind on, but take the rind away once the red part is eaten, since the green rind is hard and tough to chew.
Why it’s good
Watermelon is mostly water, so it helps with hydration in warm weather. It also gives babies vitamin C, vitamin A (as beta-carotene), and lycopene, the red plant pigment. It is low in iron and protein, so serve it alongside foods like beans, eggs, meat or yogurt to round out the meal.
Safety notes
- Remove black seeds before serving. Seeds are small and slippery and could be inhaled. Seedless watermelon still has soft white seeds, which are usually fine, but pick out any that feel firm.
- Do not let young babies bite pieces off the green rind. The rind is hard and fibrous, so use it only as a handle and take it away if baby starts chewing it.
- Wash the outside of the melon before cutting, because the knife can carry germs from the rind into the flesh. Refrigerate cut watermelon and use it within about 3 to 4 days.
- Choose ripe, soft watermelon that squashes easily between your fingers. Underripe watermelon near the rind is firmer and crunchier.
- Always seat baby upright and stay within arm's reach while they eat. Gagging is common and normal as babies learn; choking is usually silent and needs action.
A low-allergy food, still worth watching
Watermelon is not a common allergen. A small number of children react to melons, especially those with pollen allergies (oral allergy syndrome) or a latex allergy, so watch for an itchy mouth, hives, swelling or vomiting the first few times.
Watermelon for babies: questions parents ask
Quick answers about watermelon for babies and toddlers.
When can babies have watermelon?
Babies can have watermelon from about 6 months of age, once they can sit with support and are ready for solids. Watermelon is soft and juicy, so it can be mashed into yogurt or oatmeal on a spoon at first and offered as a large piece to gnaw from about 7–8 months.
Can babies have watermelon?
Yes, babies can eat watermelon from around 6 months as long as the seeds are removed and it is prepared safely for their age. Mashed watermelon on a spoon suits 6 month olds, large seedless rectangles suit babies from 7–8 months, and small soft pieces suit older babies with a pincer grasp.
Is watermelon a choking hazard for babies?
Watermelon is a low choking risk for babies when it is ripe, seedless and served in an age-appropriate shape. The main risks are the black seeds, which can be inhaled, and bitten-off pieces of the hard green rind, so remove seeds and use the rind only as a handle.
Is watermelon a common allergen?
No, watermelon is not one of the Top 9 common food allergens. Melon allergy is uncommon but can happen, especially in children with pollen or latex allergies, so watch for itchy mouth, hives or swelling.
How do I serve watermelon to a 6 month old?
To serve watermelon to a 6 month old, remove the seeds, mash the flesh and stir it into plain yogurt or oatmeal so it holds on a spoon. A seedless rectangle about two adult fingers wide to hold and gnaw can follow at 7–8 months.
Can watermelon cause diarrhea in babies?
Watermelon can loosen stools in some babies because it is high in water and contains natural sugars like fructose. Offering watermelon in normal portions as part of a varied meal usually avoids this; if diarrhea is frequent or your baby seems unwell, talk to your pediatrician.
Can babies have watermelon rind?
Babies should not eat watermelon rind because the green part is hard, fibrous and easy to bite off in chunks. A strip of rind can be left on as a handle for young babies who only gnaw, but take the piece away as soon as they start biting the rind itself.
Is seedless watermelon safe for babies?
Seedless watermelon is the easiest choice for babies because it has no mature black seeds. Seedless watermelon still has small, soft white seeds, which are usually safe to swallow, but remove any that seem large or firm.
Can babies have frozen watermelon for teething?
Frozen watermelon can soothe sore gums, but hard frozen chunks are a choking risk. Offer frozen watermelon only inside a mesh or silicone feeder, or let a large piece thaw slightly until it is soft on the outside, and stay right next to your baby.
How do I pick a ripe watermelon?
A ripe watermelon feels heavy for its size, has a creamy yellow spot where it sat on the ground, and sounds hollow when tapped. Ripe watermelon flesh is deep pink or red and soft enough to squash between your fingers, which is the texture babies need.
Is watermelon good for babies?
Yes, watermelon is a good fruit for babies from about 6 months once the seeds are removed. It is mostly water, which helps with hydration, and it gives vitamin C and vitamin A. It is low in iron and protein, so serve it alongside foods like yogurt, beans, eggs or meat.
Is watermelon good for toddlers?
Yes, watermelon is a refreshing, hydrating snack for toddlers 12 months and older, with vitamin C and vitamin A. Serve bite-size pieces or thin wedges, and take the green rind away once the red part is eaten. Keep portions normal, since a lot of watermelon can loosen stools.
