Since it's citrus I believe the general rule of thumb is close to 12 months. However, I inadvertenly gave some to my dd around 8.5/9 months - she LOVED it (still does) and was fine. US is a little more conservative - don't know where you are from? BTW - love your avatar pic....CUTE!
Two Mummies - if she liked the pineapple, maybe she'll like oranges, tangerines, or pink grapefruit? Just gave my dd some grapefruit tonight for the first time and she was very impressed.
But she eats just about everything....lol. Good luck!
