It is safe for most babies to eat tuna and other types of fish by the time they are six months of age, though there are some concerns which you will want to take into consideration before giving your child any of this fish. Some fish contains high amounts of mercury which can actually be quite dangerous and even lethal if enough of it is ingested over time. Fortunately most types of tuna do not contain a significant amount of mercury so that isnâ€™t really something you will have to worry about when it comes to giving it to your child.
There are actually many different nutritional benefits to tuna, including the fact that it has omega-3 fatty acids in it which are good brain functions. Before you give your child any fish though, you should make sure they have been fully tested for allergies and talk to your physician as well, because you cannot be too careful when it comes to your childâ€™s health.
