About Flounder

Flounder is a mild, delicate white fish that can be a great protein option for babies once they are ready to start solids. Its soft texture flakes easily after cooking, which makes it easier to serve in baby-friendly pieces than many firmer meats. It provides high-quality protein to support growth and contains nutrients such as vitamin B12, selenium, phosphorus, and some omega-3 fats that help support brain, nerve, and overall body development. Flounder is also naturally low in saturated fat and has no carbohydrates or fiber, so it pairs well with iron-rich foods, vegetables, and grains to build a balanced meal. Flounder is a common allergen because it is a finned fish. Babies with an allergy to one finned fish may react to others, so introduce it carefully and watch closely the first few times. The main safety concern is bones, which can be a choking and injury hazard, so always cook thoroughly and check the fish very carefully before serving. Most babies can start flounder from 6 months old, offered as soft cooked strips or large flakes they can pick up. As your child develops a pincer grasp, you can move to smaller deboned pieces. For toddlers, flounder can be served in bite-sized flakes, mixed into rice, pasta, or soft vegetables, always with close supervision.
