Choking risk
Butternut squash is a low choking risk once it's cooked soft - the risk comes from firm, undercooked pieces.
Cook it until you can squash a piece between two fingers, then serve smooth mash or large soft wedges; skip firm chunks and round coins. See how to serve for age-by-age prep.
Allergens
Butternut squash is not a common food allergen, so a true food allergy to it is rare.[2]
Start with a small amount and watch for a reaction.
If baby refuses
Serve it warm, not cold, and try stirring a little breast milk or formula into the mash. Mix it with a food baby already likes, like carrot or sweet potato, or offer it again in a day or two - new foods can take many tries.
How to serve

Large soft wedge or smooth mash
Wedge about the width of two adult fingers
Offer a large soft wedge for baby to grip and gnaw, or mash the cooked flesh smooth and serve it on a pre-loaded spoon. Peel the skin off first, since it can be tough. If a piece breaks off, stay calm and give baby a moment to move it forward.
How to cook
Halve the squash, scoop out the seeds, and roast cut-side down at 400°F for about 35 to 45 minutes until fork-tender, then scoop out the flesh. Or steam peeled chunks for 15 to 20 minutes. It's done when the flesh squashes easily between two fingers.

Small soft pieces
About 1/2 inch, bite-sized
Cut into small soft pieces for pincer-grasp practice, or keep offering a larger wedge alongside. It also mashes well with a little texture, stirred into oatmeal or mixed with soft-cooked lentils or chickpeas.
How to cook
Roast peeled chunks at 400°F for about 20 to 25 minutes, or steam until tender. Pieces should still squash easily between two fingers. The skin can be left on or removed now.
12+ months old
Offer bite-sized pieces alongside a fork for utensil practice. Butternut squash fits easily into family meals now - roasted wedges, mashed next to chicken or fish, or stirred into soups, risotto, pasta sauces, and curries. Mild spices like cumin, cinnamon, and nutmeg work well.
How to cook
Roast at 400°F, steam, boil, or microwave depending on the dish. With more chewing skill you can leave a little more texture, but keep pieces soft.
Tips
Roast or steam a big batch and freeze in portions; one squash makes several servings. Roasting brings out the most sweetness. Scoop out the seeds and stringy center first, and serve it warm, since cold mash is a common reason babies turn it down.
