Welcome, Sean! Sorry your baby is sick ... did your vet mention quantity of food? Our Toto is almost 17 months and 4 lbs ... she is only supposed to be eating about 1/4 cup total food per day. Seems like an awfully small quantity but when you consider how tiny her little stomach must be, I guess it all makes sense. I generally give her 1 T. in the morning and 1 T. late in the afternoon. We also leave her a tablespoon or so of dry food and plenty of fresh water available at all times [lots of water is important if they are vomiting, since they can easily dehydrate]. Keep us updated ... can't wait to see pictures and hear all about your Boo Bear!!
