The above three kinds of fish all have a common feature, that is, they have fewer spines, are easier to handle, are unlikely to cause danger to children, and are also the most beneficial species, with high nutritional value and can be absorbed by children and babies.
If it's made for children or babies, the most nutritious and healthy way is not to add all kinds of spices at will and use all kinds of cooking methods for all kinds of processing, but to use the simplest method: steaming!
Steaming (steaming on high fire 15-25 minutes, depending on the size of the fish pieces, it should be steamed thoroughly for the children to eat), which can not only lock the fishy smell of the fish, but also ensure the maximum preservation of nutrition, prevent the loss of nutrition and avoid some negative effects of various seasonings on the baby's body. You only need to sprinkle a little salt on the surface of the fish at most.
