When can babies have sardines?
From 6 months (corrected age), in the age-right form below.
- Soft, edible bones make sardines one of the best non-dairy calcium sources
- Rich in DHA omega-3s and vitamin D
- A low-mercury small fish, provides iron for the second half of the first year
How do I serve it at each age?
Safe form at 6–8 months
One water-packed, no-salt-added sardine split open, backbone lifted out, and the flesh mashed with a fork to a uniform paste that is stirred into a familiar puree or spread on a spoon.
Pass/fail test: Smear the mash between two fingers — it should feel uniformly soft with no gritty spine pieces; anything that feels like a hard fleck gets picked out or mashed again.
Why this form: Young infants need sardine delivered as a smooth mash: it removes the backbone hazard, crushes the fine bones completely, and carries the fish allergen in a spoonable, familiar-textured form.
How to prepare
- Choose sardines canned in water with no added salt; drain and split one lengthwise with a fork.
- Lift out the backbone and tail, then mash the flesh thoroughly until no distinct bone fragments remain.
- Mix into or serve alongside familiar foods, never another new food.
- First time: serve early in the day, a small amount, and watch for 2 hours.
Common mistakes
- Leaving the backbone in for a young baby — it softens with canning but can still hold its shape in a small mouth.
- Buying oil-packed or salted varieties: the sodium is the problem, not the oil.
- A rough mash with intact chunks instead of a uniform paste.
How much?
A teaspoon or two of sardine mash stirred into a familiar puree — a rich little fish, so small serves go a long way.
1–2 times a week once tolerated, counting toward the weekly fish servings.
Amounts are starting points, not targets — watch the baby, not the numbers.
How do I get the texture right?
- Read the label twice: 'in water, no salt added' is the phrase you want — most sardine cans are brined or packed in salted oil.
- Mash with the back of a fork against the side of a bowl; a proper mash crushes the fine bones so completely you can't feel them.
- Sardines are among the lowest-mercury fish available, an easy pick for the couple of weekly fish servings recommended for young children.
- Mashed sardine disappears into tomato-based pasta sauce — a painless route for babies who balk at fish flavor on its own.
Is sardines a choking hazard?
Choking care
The backbone and any intact spine segments are the hazard for early eaters, along with firm unmashed chunks. Mitigate by splitting each sardine, lifting out the backbone for babies under 12 months, and mashing the flesh thoroughly — the remaining hair-fine bones crush safely when the fish is well mashed.
Is sardines a common allergen?
Common allergen: Fish
Yes — introduce it early in the day, alongside familiar foods, and watch for 2 hours. See the Fish introduction program →
Anything to watch for?
Most cans are brined or packed in salted oil — 'in water, no salt added' is the label that keeps sodium in check.
What nutrients does it bring?
Iron tip: vitamin C boosts iron absorption — pair with apple, apricot, bell pepper.
