Quick answer
Babies can eat sardines from around 6 months, as soon as they start solids and show readiness signs such as sitting with support, steady head control, and bringing food to the mouth. Sardines are small, short-lived fish near the bottom of the food chain, which keeps their mercury among the lowest of any fish, and both the AAP and NHS encourage oily fish as part of a varied diet from the start of solids. Canned sardines are already fully cooked, and fresh sardines just need to be cooked through until the flesh flakes.
When can babies eat sardines?
Babies can eat sardines from around 6 months, as soon as they start solids and show readiness signs such as sitting with support, steady head control, and bringing food to the mouth. Sardines are small, short-lived fish near the bottom of the food chain, which keeps their mercury among the lowest of any fish, and both the AAP and NHS encourage oily fish as part of a varied diet from the start of solids. Canned sardines are already fully cooked, and fresh sardines just need to be cooked through until the flesh flakes.
Fish is a top-9 allergen, so introduce sardines the way the AAP recommends for allergens: early, in a small amount, and alongside foods your baby already tolerates, then watch for reactions such as hives, vomiting, wheezing, or an eczema flare-up over the next few days. Once sardines are tolerated, keep them in regular rotation, since ongoing exposure helps maintain tolerance. The NHS suggests up to 2 portions of oily fish a week, and 1 to 2 baby-sized servings of sardines weekly fits neatly inside that.

Safety Tips
- ✓Fish is a top-9 allergen: offer a small amount of sardine on its own the first few times and watch for hives, vomiting, wheezing, or an eczema flare-up over the following days, in line with AAP early-introduction guidance.
- ✓Canned sardine bones are soft, edible, and rich in calcium once mashed thoroughly; fresh sardine bones are not, so check cooked fresh sardines meticulously and remove every fine bone before serving.
- ✓Watch the salt: choose sardines canned in water with no added salt where possible, rinse them before serving, and skip brine-packed tins and salty sauces, since babies under 2 should have minimal salt.
- ✓Sardines are among the lowest-mercury fish, and the NHS advises up to 2 portions of oily fish a week; 1 to 2 small servings of sardines weekly is a good rhythm.
- ✓Cook fresh sardines all the way through until the flesh flakes easily, and always supervise meals with your baby seated upright.

How to serve sardines for a 6 month old
At 6 months, the easiest route is canned sardines packed in water: rinse them under cool water to wash off surface salt, then mash them thoroughly with a fork, soft bones and all, into mashed potato, sweet potato, or a pea and vegetable mash. The bones in canned sardines are cooked so soft they crush between your fingers, and mashing them in is exactly what you want, since they carry most of the calcium; just work the mash until no gritty flecks remain. Aim for a moist, cohesive texture your baby can scoop by hand or take from a preloaded spoon, using about half a sardine to one sardine stirred through a few tablespoons of mash. If you cook fresh sardines instead, bake or grill them until the flesh flakes, then check meticulously for the fine spine and rib bones and remove every one before mashing. Keep it plain with no added salt, and supervise with your baby seated upright.
