He had some oatmeal with raisins, coconut
milk and sugar (we are vegetarian/vegan),
and about 10 mins later, he started the same thing again. Nauseousness, and then he vomited once. Then fell asleep.
During the day he eats the same things he has always been eating. Mainly tofu, breads, rice, beans, and other snacks. I try to give him lots of water. He prefers juice and is always thirsty, and asking for juice.
