Riley has been having raisins, cranberries etc for a long time now, since before 18 months, I think? Can't quite remember.
The popcorn I believe is considered a choking hazard til well gone the 3 year mark. The advice on peanut butter vaires depending on where you live. Some say it's okay thinly spread on something when they are a year old, in other countries it is advised to skip it until 3 years. For allergy and choking reasons.
Riley (28 months) had some mini marshmallows today and loved them!
