I also find that my dd doesnt like fruit from a jar much (its so bitter isnt it). I either add a small amount to her porridge in the morning or cereal, another thing you can do is like the lady above said, add some to a petit filou or natural yoghurt. I also think that if you make your own puree its not as acidy and that may be a good idea to. Sometimes I add a small amount of fruit puree to a rusk that ive pre mixed with either formula milk or cool boiled water. This way your child gets the goodness of the fruit but doesnt gag because its too acidy. The faces my dd pulls when I first tried her on apple and pear from a jar were worth filming and sending off to a candid camera tv programme. haha its all fun and games isnt it. x
Another thing you can try is adding a little puree to some baby rice?
good luck and keep us posted
