Fish can offer your child a wide array of great nutrients, vitamins, and benefits like omega 3’s and protein that can directly affect the health of your brain and your heart. Fish is even referred to, by many people, as brain food. However, when it comes to your baby before they are a year old, fish is better left off of the menu. The problem is that a lot of the fish that is typically found in the home has a high chance of containing elevated levels of mercury. The types of fish that usually contain high levels of mercury that you should avoid feeding baby is tuna, mackerel, swordfish, and shark. If you and your family typically have a diet high in fish, tilapia, trout, and haddock are good options. Fish is also not recommended for children under a year old because, like most seafood, fish is a common allergy.
