Quick answer
Babies can eat soba from around 6 months, once they show signs of being ready for solids. Prepare it as shown below.
How to serve soba by age
6 months+
A small bundle of soft noodles
Cook soba in plenty of unsalted water a little past the package time, until very soft. Drain, rinse in cool water so the strands don't clump, and offer a small bundle plain or tossed with a smooth sauce with no added salt. Most soba contains wheat, so offer it once your baby has had wheat on its own.
- Size
- A small bundle of soft noodles cut to about the size of an adult finger, roughly 6–8 cm long and 2 cm wide (2½–3 × ¾ in), or cut short and mashed into soft vegetables.
- Check before serving
- Squash a noodle between your thumb and finger. It should flatten easily, with no firm center.
US and UK advice differ here. The AAP suggests mashed food or soft pieces no larger than ½ inch; the NHS suggests soft finger-sized pieces your baby can hold in their fist. Both agree the food must squash easily.
9 months+
Short soft pieces
Chop soft noodles into short pieces for pincer-grasp practice, and mix them with soft vegetables, soft tofu, or flaked fish once your baby has had fish on its own.
- Size
- Pieces no bigger than about 1 cm (just under ½ inch).
- Check before serving
- Each piece should squash flat between your thumb and finger.
12 months+
Soba in family meals
Serve soft soba in a cooled noodle soup or with soft vegetables. Take your toddler's portion out before soy sauce or dipping sauce goes on, and cut long noodles short.
- Size
- Short pieces about 1 cm (just under ½ inch), or short strands.
- Check before serving
- Still do the squash test: soft enough to flatten with gentle pressure.
18 months+
Any soft soba dish
Offer soba the way your family eats it, warm or cold, cooked soft and cut short. Keep dipping sauces and soy sauce out of your child's bowl, and cut mix-ins small and soft.
- Size
- Bite-sized pieces about 1 cm (just under ½ inch), or short strands.
- Check before serving
- Noodles should flatten easily, and mix-ins should be soft.
Always have your child sit upright in a high chair or at the table, and stay with them the whole time they eat. Keep to the size and texture for their stage. Every baby develops on their own timeline.
How to prepare soba
- 1
Check the label. Most soba is made from wheat and buckwheat flour, some is 100% buckwheat, and many packs add salt.
- 2
Boil soba in plenty of water with no salt, a little longer than the package says, until a noodle squashes easily between your fingers. Drain and rinse in cool water so the strands don't clump.
- 3
Cut the noodles to the right length for your baby's stage, and serve them plain or with a smooth sauce with no added salt.
- 4
First time? Pick a day your baby is well, at home, when you can watch them for a couple of hours afterward.
How much to offer
For the very first taste, offer a few strands. If there's no reaction, offer more next time. Your baby decides how much to eat: stop when they turn away or close their mouth. Once wheat is in your baby's diet, keep offering it regularly.
Common mistakes
Assuming soba is wheat-free
Buckwheat isn't wheat, but most soba noodles also contain wheat flour, often as the first ingredient. If the label lists wheat, offer soba only after your baby has had wheat on its own. For a child with a wheat allergy or celiac disease, look for 100% buckwheat noodles labeled gluten-free.
Adding soy sauce or dipping sauce
Babies shouldn't have added salt or salty foods (NHS). Keep soy sauce and soba dipping sauce for adults' bowls.
Cooking them firm
Firm noodles are too hard for babies. Cook soba until a noodle squashes easily between your fingers.
Serving long, slippery noodles
Long noodles are slippery and hard for babies to manage. Cut them with kitchen scissors: finger-length bundles at 6 months, short pieces about 1 cm (just under ½ inch) from 9 months.
Questions parents ask
Can soba be a choking hazard for babies?
Well-cooked noodles are a low choking risk, and the NHS lists noodles among first finger foods. Firm, undercooked noodles are harder to manage, so cook soba soft, and cut long strands short for babies and young toddlers. Stay with your child during meals.
Can babies be allergic to soba?
Most soba contains wheat (with gluten) as well as buckwheat, so we list wheat as its allergen: check the label. Wheat can be introduced from around 6 months: offer it on its own first, in a small amount, and watch for signs of a reaction. Buckwheat isn't one of the top 9 US allergens or on the NHS list of foods that commonly trigger allergy. Buckwheat allergy is considered rare outside Asia, but it's a common cause of life-threatening allergy in Asia, and in a Japanese hospital study of children who were already suspected of buckwheat allergy, about half of those who reacted during a food challenge had anaphylaxis. Our suggestion, if you can: offer buckwheat on its own first, such as smooth buckwheat porridge, before soba. Wheat allergy is different from celiac disease, a digestive condition triggered by gluten.
Is soba healthy for babies?
Cooked soba has about 5 g of protein per 100 g, a little iron (about 0.5 mg) and about 60 mg of sodium (about 0.15 g of salt). Dried soba varies by brand: one brand's wheat and buckwheat soba has about 554 mg of sodium per 100 g (about 1.4 g of salt), while one brand's 100% buckwheat noodle has about 9 mg (about 0.02 g of salt), so compare labels. The NHS says babies under 1 should have less than 1 g of salt a day, and children aged 1 to 3 no more than 2 g.
Is soba gluten-free?
Only if it's 100% buckwheat and labeled gluten-free. Buckwheat itself is gluten-free, but most soba also contains wheat flour. Read the full label, especially for a child with celiac disease or a wheat allergy.
Can babies eat soba at 6 months?
Yes, once your baby has had wheat on its own, since most soba contains wheat. Cook it very soft in unsalted water, cut it to about finger length, and start with a few strands.
Is soba salty?
Some is. Many soba packs list salt: one brand's wheat and buckwheat soba in FoodData Central has about 554 mg of sodium (about 1.4 g of salt) per 100 g before cooking. The NHS says babies under 1 should have less than 1 g of salt a day, and children aged 1 to 3 no more than 2 g. Boil soba in plenty of unsalted water, compare labels, and skip the dipping sauce.
If your baby refuses soba
- Many babies need 10 or more tries before they accept a new food. Keep offering it alongside foods they already like.
- Try shorter pieces, or toss the noodles with a sauce your baby already likes.
- Eat some yourself at the same meal. Babies copy what they see.
- If your baby keeps refusing soba, offer buckwheat as a smooth porridge, or wheat as soft pasta or toast strips.
Never force or pressure your baby to eat. Some days they'll eat more, some days less, and that's normal.
Buying and storing soba
- Keep dry soba in a sealed container in a cool, dry place.
- Cooked soba keeps for 3 to 4 days in a covered container in the fridge.
- Cooked soba can be frozen for 3 to 4 months. Reheat only once, to 165°F (74°C), until steaming hot, then let it cool before serving.
- Throw away any food left out at room temperature for more than 2 hours (1 hour if it's hotter than 90°F / 32°C).
When to talk to your doctor
Contact your pediatrician, GP or health visitor if:
- Your baby has had any reaction to soba, wheat or buckwheat, even a mild one. Stop offering soba until you've talked to your pediatrician.
- Your child has ongoing diarrhea, tummy pain or bloating, or isn't growing as expected, while eating foods with gluten. These can be signs of celiac disease.
- You notice mild signs of an allergic reaction after eating, such as a few hives or a little vomiting. See signs of a reaction.
- You're worried about how much your baby eats, their growth, or they refuse most solid food for weeks.
Call 911999your local emergency number (such as 112 in Europe or 000 in Australia) now if your baby has trouble breathing, wheezing, can't cough or cry, has lips, mouth, tongue or throat that suddenly swell, or becomes pale, bluish, floppy or unresponsive. Also call if hives come with repeated vomiting.
