Sweet potato for babies: when to start, mash and soft wedges

Sweet potato is a common first food, and it suits both spoon-feeding and baby-led weaning. It can be offered from around 6 months, once your baby has started solids. The NHS first solid foods guide suggests it mashed or as soft, cooked sticks, and the CDC lists it among the vegetables to encourage for children from 6 months.

The key is cooking it soft all the way through, then moving from mash to soft wedges and fingers as your baby's skills grow. This guide covers when to start, steamed versus baked, how to prepare it at each stage, what it adds nutritionally, which iron-rich foods to pair it with, and how to keep meals safe.

When can babies eat sweet potato?

From around 6 months, once your baby shows the signs of being ready for solids described in starting solids.

The Australia's ASCIA guide to introducing solid foods, from Australia's allergy body, says iron-rich foods should be offered at around 6 months and other solid foods can be introduced in any order. Australia's Pregnancy, Birth and Baby, which lists the national Infant Feeding Guidelines among its sources, includes puréed fruit and vegetables among first foods. The CDC's foods and drinks for 6 to 24 month olds says babies can start foods other than milk around 6 months, and its foods to encourage include cooked spinach, carrots, peas, lentils and sweet potatoes.

Should sweet potato be the very first food?

It can be one of them, but not the only one. The NHS guide to feeding from around 6 months suggests starting with vegetables that aren't so sweet, such as broccoli, cauliflower and spinach, rather than just the sweeter ones like carrots and sweet potato, so your baby gets used to a range of tastes. In Australia, ASCIA puts iron-rich foods first. Sweet potato works well mixed with both.

Should I steam, boil or bake sweet potato for my baby?

Any of these works, as long as it ends up soft all the way through. The sources describe more than one method:

• Steaming or simmering. The NHS guide to preparing food safely suggests softening firm vegetables by steaming or simmering until soft, then cutting them into slices or narrow batons. Australia's Pregnancy, Birth and Baby suggests vegetables cooked with a small amount of water.
• Roasting or baking. Australia's ASCIA lists roasted vegetable wedges, as well as steamed vegetables, among suitable finger foods.

Whichever method you choose, test it. New Zealand's Ministry of Health, in its advice on reducing food-related choking, describes soft food as food that can be easily squashed between your thumb and forefinger, or on the roof of your mouth with your tongue. Roasted pieces sometimes pass the test in the middle but not at a browned, chewy edge, so press the ends too.

The AAP's starting solids page says fresh foods should be cooked with no added salt or seasoning. The NHS says to make sure cooked food has cooled right down, and to test it, before offering it to your baby.

How do I prepare sweet potato at each stage?

1. Wash and peel. Rinse it under running water, as the CDC's food-safety advice suggests for fresh produce, then peel it, or bake it whole and scoop out the flesh.
2. Cook until very soft by steaming, boiling, baking or roasting, with no salt.
3. Shape it for your baby's stage using the table below.
4. Cool and test the temperature before serving.

Around 6 months. The NHS suggests mashed or soft, cooked sticks of vegetables such as sweet potato. It says finger food works well in pieces about the size of your own finger, big enough to hold in a fist with a bit sticking out. A long, soft wedge is easier for a young baby to grab than a small cube.

8–9 months. The NHS guide for 7 to 9 months suggests more mashed, lumpier foods and a variety of finger foods. Roughly mashed sweet potato with soft lumps, and soft wedges or cubes, both fit here.

12 months and beyond. Australia's ASCIA says to aim for your baby to be eating soft, cut-up or roughly mashed family meals by 12 months. Sweet potato works in curries, stews and traybakes; take your child's portion out before adding salt or stock.

The NHS 7 to 9 months guide also says shop-bought pouches and jars shouldn't be relied on as an everyday food. Homemade sweet potato mash is quick, and freezes well in small portions. For how textures progress overall, see food textures, and for the two feeding styles, baby-led weaning vs purées.

Is sweet potato a choking risk?

Cooked soft, it's one of the gentler textures. Raw or undercooked, it isn't. The CDC's choking hazards list includes pieces of hard raw vegetables, and the CDC's solids guide says to cook hard vegetables so they can be easily mashed. Australia's Pregnancy, Birth and Baby lists uncooked vegetables among small hard foods that babies can choke on, and says babies can choke on food of any texture.

Watch out for:

• Hard, undercooked centres or browned, crunchy edges on roasted wedges
• Sweet potato crisps, which are like the potato and corn chips the CDC lists among choking hazards
• Thick, sticky mash. The CDC says to avoid sticky foods that are difficult to chew and swallow, so loosen mash with a little milk or cooking water

Set every meal up the same way. The CDC says to keep your child sitting up while eating, watch them the whole time, and avoid eating in the car or pram. Gagging on soft wedges is common while babies learn; choking vs gagging explains the difference.

These steps follow the NHS choking first-aid guide, which also says to get medical help afterwards even if the food came out. The Royal Children's Hospital Melbourne in Australia says anyone caring for young children should do a children's first-aid course, and the AAP's choking-prevention advice recommends a certified CPR and first-aid course. Doing one before or soon after starting solids means you've practised the steps.

What nutrients does sweet potato give my baby?

The NHS vitamin A page lists sweet potatoes, carrots, spinach and red peppers among foods containing beta-carotene, which the body can convert into vitamin A (retinol). The NHS says vitamin A helps the immune system work, helps vision in dim light, and keeps skin healthy. The CDC's iron page also lists sweet potatoes among vitamin C-rich foods.

Food doesn't replace the vitamin supplements recommended where you live. In the UK, the NHS first solid foods guide recommends vitamins A and C, as well as vitamin D, from 6 to 12 months for breastfed babies and babies having less than 500 mL of formula a day, and vitamins A, C and D for all children aged 1 to 4. Advice differs by country; vitamin D for babies explains what applies where you live.

Why has my baby's skin turned slightly orange?

Lots of orange vegetables can do this. La Leche League describes carotenemia, an orange tinge to the skin from eating a large amount of carotene, found in foods such as carrots, squash, sweet potato and pumpkin. It says it's most often seen in babies and toddlers, that cooking and mashing increase how much carotene is absorbed, and that it's nearly always harmless and isn't vitamin A poisoning. Offering a wider mix of foods is the usual fix.

An orange tinge with normal, white eyes is different from jaundice. The NHS jaundice page lists yellow skin or yellow whites of the eyes, darker pee and paler poo as signs, and says to get an urgent GP appointment. If the whites of your baby's eyes look yellow, their poo is pale, their wee is dark, or they seem unwell, get medical help today.

Which iron-rich foods go well with sweet potato?

Sweet potato isn't one of the iron-rich foods. Australia's ASCIA lists iron-fortified cereals, meat, poultry, fish, well-cooked egg, tofu and legumes such as chickpeas and lentils as the iron-rich foods to offer from around 6 months. The CDC says pairing vitamin C-rich foods with plant sources of iron helps babies absorb it, and sweet potato is on its vitamin C list. Some pairings to try:

• mashed sweet potato with minced beef, lamb or chicken
• sweet potato and red lentils cooked together and mashed
• soft sweet potato wedges alongside strips of well-cooked omelette
• sweet potato mash stirred through iron-fortified infant cereal
• soft cubes of sweet potato and tofu

First foods and iron explains why iron matters from 6 months, and avocado is another soft first food that pairs well.

Can babies be allergic to sweet potato?

It's possible with any food, but sweet potato isn't on ASCIA's list of the most common allergy foods in Australia: cow's milk, egg, peanut, tree nuts, wheat, soy, sesame, fish and shellfish. Australia's ASCIA says allergic reactions usually happen within minutes to two hours, and that a mild rash only around the mouth, with no other signs, may not be an allergic reaction. The CDC suggests one new single-ingredient food at a time, with 3 to 5 days between new foods, so it's easier to spot what caused a reaction. Introducing allergens covers the common allergy foods.

When should I get help?

Call 999 now if your baby:

• can't breathe, cough or cry because food is stuck, turns blue or becomes unresponsive
• has sudden swelling of the lips, tongue or throat after eating
• has difficult or noisy breathing, a wheeze or a persistent cough after eating
• becomes pale, floppy or drowsy, collapses, or has a hoarse or weak cry

The NHS urgent-help guide lists swollen lips, tongue or throat and difficulty breathing among reasons to call an ambulance. For these signs of anaphylaxis, the Australia's ASCIA first aid plan for anaphylaxis from Australia says to hold young children flat, not upright, give an adrenaline device if one has been prescribed, call an ambulance, and start CPR if your baby is unresponsive and not breathing normally.

Get medical help today if your baby:

• has hives beyond the mouth, swelling of the face or eyes, or vomits after a food, and is breathing normally
• needed back blows or chest thrusts, even if they now seem well
• has yellow whites of the eyes, pale poo or dark wee

Talk to your GP or health visitor if:

• your baby's skin looks orange and you'd like it checked
• your baby still can't manage mashed or lumpy food by around 9 months
• you're worried your baby isn't getting enough iron
