Just occured to me having been reading this thread here that it might be worth pointing out just how bad raisins and other dried fruits can be for children's teeth.
Another mum had told me that in terms of dental health, you're better off giving your child chocolate than dried fruit, as it doesn't stick to the teeth and the saliva washes away more of the sugary residue.
It seems time of day is crucial for when they eat dried fruit and fruit juices. The key is to stick to just before they are likely to have their teeth cleaned, or be eating a bigger meal (so breakfast and tea time really).

Sorry if this is coals to Newcastle territory, but I thought it was info worth sharing.
