Can babies eat plaice? Yes, from around 6 months once solids are underway. Plaice is a mild, delicate flatfish that cooks quickly and flakes into soft, tender pieces, which makes it a gentle first fish. It is low in mercury, so you can offer it fairly regularly. The two jobs that matter most are cooking it through and going bone-hunting before it reaches the tray, since plaice fillets can hide fine pin bones.
Why it matters: A mild, low-mercury flatfish makes a gentle first fish once it is cooked through, kept moist, and every bone is removed.

Is plaice safe? Choking & prep
Fish is one of the top-9 allergens, so introduce plaice deliberately, on its own, and watch your baby for a few days before adding other new foods.1 Cook it through until it flakes and is opaque, then flake it and check meticulously for bones, since even a small fish bone is a serious choking and injury risk. Keep the flakes soft and moist with a little cooking liquid or a mash so they are easy to swallow, and offer no hard chunks. Add no salt, as babies need very little sodium under age 1.

Nutrition
Plaice is a lean source of high-quality protein and brings vitamin B12 and selenium, which support growth, a healthy nervous system, and a developing immune system. It carries some omega-3 fats too, though less than oily fish like salmon, so think of it as a lean-fish pick and rotate in oilier fish across the week for more omega-3. Being low in mercury, plaice is one of the fish you can offer fairly regularly once every bone is out and it is kept moist.
Goes well with
Mashed potato · Rice · Peas · Steamed carrot · Cooked spinach
Storage & freezing
Refrigerate cooked plaice and use within a day, or freeze fresh fillets until you are ready to cook them. Reheat gently and add a little liquid to keep the delicate flakes from drying out.

Common questions
When can babies eat plaice?
Around 6 months, once solids are underway. Because fish is a top-9 allergen, introduce plaice on its own the first few times and watch for a reaction over the next couple of days.
Is plaice safe for babies?
Yes, when it is cooked through and fully deboned. Plaice is low in mercury and mild, which makes it a gentle early fish.
Is plaice high in mercury?
No. Plaice is a low-mercury fish, so you can offer it fairly regularly rather than saving it for once a week. Ask your pediatrician if you are unsure how often to serve fish.
Do I really need to remove every bone?
Yes. Cook the fillet, break it into small flakes, and press each one between your fingers in good light, since plaice can hide fine pin bones and even a small one is a serious choking and injury risk.
How do I keep plaice from being dry?
The fillets are thin and cook fast, so poach or bake gently, avoid overcooking, and keep the flakes moist with a little cooking liquid or a soft mash.
What are the signs of a fish allergy?
Watch for hives, swelling, vomiting, or trouble breathing after eating. If you see any concerning reaction, stop and contact your pediatrician; for trouble breathing, call emergency services.
Can babies eat plaice if there is a family history of allergies?
Often yes, and delaying allergens does not prevent allergies. If your family has a strong history of food allergy, talk with your pediatrician about the best way to introduce fish for your baby.
How should I cook plaice for a baby?
Bake or poach it plain, with no salt, until it flakes easily and looks opaque all the way through. Then flake it, remove every bone, and keep it moist.
Does plaice have much omega-3?
Some, but less than oily fish. For more omega-3, rotate in salmon or mackerel across the week alongside lean fish like plaice.
