Day and Night

I finally figured out Karston's sleeping pattern! He's not sleeping through the night, but he does know that it's time to sleep when it's dark. He'll wake up every two hours to nurse (sometimes every hour, once in while every three hours), but he will go back to sleep after a quick meal. And that's the problem ... he knows about nighttime for sleeping, but he hasn't figured it out for eating. He only snacks at night, but he'll have a full meal during the day. He's got day for night reversed for his meals! Aha! Now how to convince someone to eat more when he seals his lips and moves his head away ...
