The UK NHS has no restrictions on feeding them after 6 months, however, I would give tomatoes cooked to start with (less likely to cause a reaction) and give oranges as small pieces of finger food either with the inner 'skin' removed or chopped up small. Just be aware they are both foods which can cause reactions so keep an eye on it. Also be careful not to attribute every tiny thing to a food allergy. I was sure my son reacted to egg and raw tomato the first times he had it but then he was fine later. It could have been that he just had a mild reaction and is now fine or just some unassociated patch of eczema that I attributed to the food but was unrelated.
