Something you might consider is that your child if they are eating solids might be getting this fatty acids from food, which is perhaps why they are all saying the "gold" brands are important before 6 mths and not as important afterwards. Just a thought? Then again most food that is consumed before 9 mths is just really fibre and water (veges, fruit and rice stuff!) it's not until they start eating meat, eggs, and the other things mentioned that it would replace what is needed. Perhaps until your child is eating enough of that type of food to receive the nutrients?
