To the child of 2 years old, practically nothing is eaten. I tried everything, but refuses food from his mouth and all. From vegetables eats fresh tomatoes and cucumbers, from fruits only grapefruits. At night drinks Bio with a bottle of 800 gr, during the day does not want to eat. What vitamins can be given for appetite increase? The neighbor's children were also little eaters, she gave them vitamins in drops, said that they help well, but the name is forgotten.
