mandy,
I gave Hao Re raisin last week. He loves it, asking for more and more, but I limit the number, think only gave him 10 raisins per day. We can give ANYTHING AND EVERYTHING (again, if your boy doesn't have allergy/asthma,etc) to our boys this age, it's only our choice to let them try now or later. Up to you to decide. For me, I have loosen the "rules" more and more, now we let Hao Re try almost everything we eat. He is okay so far, and still willing to eat his bland porridge, luckily.
