Did anyone see the article on canned tuna in the times magazine yesterday? Saying that it is not a good source of omega 3 oils due to the canning process, but also implying that it is not safe for children due to the high levels of mercury which once absorbed can lead to learning difficulties. I have been giving my 9 month old ds tuna for about a month as had been advised that he could start having oily fish, although I knew it is advised not to have too much whilst pg, it never occured to me that it might not be safe for him to eat now. I am worried it's been doing him more harm than good - or is it yet another food scare?!
