Foxgluvs, check out the Haliborange Omega 3 Fish Oil capsules, which you can find in Boots - they are chewy and more like eating a 'sweet', so perhaps your daughter might find them easier to take. There is an orange flavoured capsule and also a blackcurrant one, which according to my DD tastes great and not at all fishy.

There's also Haliborange Omega-3 Fish Oil Twistie Fish - fun fish-shaped 'twist-off' capsules developed for children who prefer not to chew or swallow capsules and are filled with delicious orange fruit paste.

You can check these out on the boots.com site, if you need want any further info etc., and also at the Haliborange site
