Allergen note
Flounder is a fish, and fish is one of the common food allergens. From 7 months, offer a small amount of well-cooked flounder on its own and watch for hives, swelling or vomiting; once it is tolerated, keep offering it regularly. If your baby has severe eczema or a known food allergy, talk to your pediatrician first.
How to serve
Flounder is a mild, low-mercury white fish that flakes very easily. At 7–8 months, mix flakes into mashed potato or vegetable purée, or offer large, soft flakes to pick up; from 9 months, offer small flakes for pincer practice; toddlers can eat it with a fork. Fish can be offered about twice a week.
Preparation
Bake, steam or poach flounder fillets until the flesh is opaque all the way through and flakes easily with a fork (145°F/63°C). Skip salt and salty sauces; a little olive oil, lemon or dill adds flavor. Refrigerate leftovers promptly and use them within 2 days.
Texture and choking risk
The main hazard in flounder is small bones, especially the fine bones along the edges of the fillet. Break the cooked fish apart with your fingers to feel for bones before serving, keep the flakes moist, and always supervise while your baby sits upright.

Starting ages are typical guidance for healthy, full-term babies who show signs of readiness. Your paediatrician may advise differently, especially where there is a family history of allergy.
