🐟 Weaning (6-12 months)
Baby's First Fish Pie Mash
By Emma Whitfield · Pregnancy & Baby Writer
Fish is one of the allergens the NHS recommends introducing within the first year rather than delaying, and a soft mash like this is a gentle way in once you've confirmed your baby tolerates fish on its own.
Ingredients
- 100g skinless white fish fillet (e.g. cod or haddock)
- 1 medium potato, peeled and chopped
- 2 tbsp frozen peas
- 2-3 tbsp whole milk
Method
- Boil the potato for 15 minutes until soft.
- Meanwhile, poach the fish in a separate pan of gently simmering water for 8-10 minutes until opaque and flakes easily.
- Check the fish thoroughly for any bones, flaking it apart carefully with a fork.
- Cook the peas in the last 3 minutes of the potato's cooking time, then drain everything together.
- Mash with the milk to your baby's preferred texture.
Tips
- Introduce fish alone first, in a small amount, and wait a few days before combining with other new foods — standard allergen-introduction practice.
- Salmon works well as a swap and adds omega-3s; check just as thoroughly for bones.
Weaning safety reminders
No honey before 12 months (infant botulism risk). No added salt or sugar. Cut round foods (grapes, cherry tomatoes) in quarters, not halves. Always supervise your baby while they eat, sitting upright, and check food has cooled to a safe temperature.
