Can Babies Eat Mashed Potatoes? Yes, From 6 Months

Mashed potato is the friendliest thing on the Thanksgiving table for a baby. Soft, mild and easy to thin, it works from about 6 months. The three things to manage are added salt, the dairy stirred through it, and a stiff gluey texture. Scoop the baby portion out before the salt and gravy go on.

When to introduce

From about 6 months, once your baby can sit upright with support and is starting solids.

Common allergen?

Potato itself is not a common allergen. The butter, cream or milk mashed into it is milk, one of the nine major allergens the FDA requires on labels. Gravy adds wheat, because it is usually thickened with flour.

Texture

Soft and spoonable. Thin it with breast milk, formula or the cooking water so it drops off a spoon, because dense sticky mouthfuls are harder for a new eater to move around.

Key nutrients

Carbohydrate for energy, plus potassium, vitamin C and fiber, with more fiber if some skin stays in for older babies.

Yes, babies can eat mashed potatoes, and from about 6 months this is one of the best things on the holiday table for them. It is soft, it is mild, it needs no chewing, and it takes almost no work to make baby-friendly. The catch is that holiday mashed potatoes are not plain mashed potatoes. They get salted in the pot, loaded with butter and cream, salted again at the table, and then covered in gravy, which is usually the saltiest thing in the room. Babies under a year do not need any added salt. So here is your sentence for standing in someone else's kitchen: "Can I take a spoonful out before you salt it?" Ask it while the pot is still on the stove and you have solved almost the whole problem in one move. Thin that plain scoop with a splash of breast milk, formula or the potato water until it is loose, and your baby is eating the same dish as everyone else.

Are mashed potatoes safe? Choking & prep

Mashed potato is one of the lower risk foods you can hand a baby, so the cautions here are about what gets added to it rather than the potato itself. Salt is the big one. The CDC advises avoiding foods high in sodium for young children, and AAP guidance for babies starting solids is that fresh foods should be cooked with no added salt or seasoning, which rules out the salted pot, the stock cube and the gravy boat. Plate your baby's scoop before any of that goes in. Gravy is worth naming separately: it is built on stock and drippings, it is usually the saltiest thing on the table, and because it is thickened with flour it also carries wheat, which matters if wheat is new for your baby. Texture is the second thing. Mash whipped in a food processor turns dense and gluey, and the CDC groups sticky foods with hard ones as the ones that are difficult for a young child to chew and swallow, so mash by hand and thin it with liquid until it is loose. Thinning it reduces that risk rather than removing it, so keep your baby sitting upright, stay beside them, and let them set the pace. Third, the dairy. Butter, cream and whole milk are what make mashed potato taste like mashed potato, and milk is one of the nine major allergens the FDA requires on labels. If your baby has not had dairy yet, a holiday table is a poor place to meet it, so offer a spoon of plain yogurt on an ordinary day first and you will be able to tell what caused any reaction. Fourth, the thing nobody thinks about at a holiday: how long the bowl has been sitting out. Mash usually goes on the table early and stays there all afternoon, and the CDC says never to leave perishable food out for more than 2 hours, or 1 hour above 90F. Serve your baby from a portion you put aside and refrigerated, not from the bowl that has been on the table since noon. Last, check the temperature. Mash holds heat in the middle long after the top feels cool, so stir it through and test it on your own lip before it reaches the tray.

Nutrition

Potatoes are mostly carbohydrate, which is exactly what a crawling, cruising baby burns through in a day. The USDA seasonal produce guide's nutrition panel for a medium potato shows fiber, potassium and vitamin C alongside that carbohydrate, and for an older baby leaving some skin in the mash keeps more of the fiber than peeling everything. That vitamin C is quietly useful at a holiday meal, because vitamin C helps the body take up the iron in plant foods, so the mash is doing the beans and greens next to it a favor. The fat you stir in is not the enemy either. Babies need a high proportion of fat in their diet, so unsalted butter or a splash of whole milk after 12 months is doing useful work rather than undoing the vegetable. What mash does not bring is iron, so it belongs beside shredded turkey, soft beans or chicken rather than standing in as the meal.

Goes well with

Turkey · Green beans · Peas · Carrot · Chicken · Applesauce

Storage & freezing

Cool leftover mash quickly, get it into an airtight container and into the fridge within two hours, then use it within 3 to 4 days. Reheat until it is steaming hot all the way through, stir hard to break up hot spots, then let it cool to warm before it goes near your baby. Mashed potato freezes better than people expect when there is some fat in it, so freeze baby sized portions in an ice cube tray, bag the cubes, and thaw them in the fridge overnight. Do not refreeze mash you have already reheated, and throw away anything your baby has had their spoon or hands in, because saliva in the container speeds up spoilage.
