The amount depends on their appetite at any given time, but since they're pretty small I'll bet a 2-3 month old can go through a lot at once. Don't be surprised if they can put away 20-30+ at a sitting, but this will vary. Sometimes they eat too quickly and don't chew them, so they pass through undigested. Not harmful, but kind of a waste so look out for that. You can hand feed them to slow down their eating and encourage more chewing, but that can be time consuming.
