I would definently say something and 10-15 min is a crappy amount of time for a child of any age to have to eat much less a little one. We homeschool and my 6 year old is horrified at the idea that kids in public school can't eat throughout the day. I can't imagine how grumpy my child would be without lots of snacks throughut the day. I can't see the small kids being able to do their best on a nearly empty stomach.
