I feed my babies twice a day. Once in the morning then once around 5 or 6 p.m. I usually feed the same amounts each time so there's no accidents during the day when I am away at work OR during the night. When I first got them, about 2 years ago, I free fed. That didn't work because they wouldn't eat the dry food alone (without some moist mixed in) and leaving it set out all day wasn't good at all.
