My son is 15 months old, and has been eating an increasing variety of solid foods. However, we are having a hard time getting him to eat normal "meals".
His favorite foods are more in the category of "snacks"; particularly dry cereal, whole wheat "gold fish" crackers, pretzels and (most recently) tortilla chips (and salsa). However, at meal times he tends to get hungry before we're ready, and frequently fills up on milk or snacks while we're waiting for the meal to be ready.
The end result is that he'll eat mostly milk, and carbs. Even when he does a good job eating, when we're not at home his meal will include mostly bread or grains (he loves toast, crackers, grilled cheese sandwiches, and even tortilla chips), and only a couple of bites of meat (roughly the equivalent of a single chicken "finger" or strip), and, if we're lucky, assorted bites of vegetables, rice, or beans.
At home we do tend to have better results in making sure he gets fruit (applesauce is usually easy to get him to eat) and vegetables, but it can still be difficult.
For the first year, the rule of thumb was "nutrition comes from formula". Now that he's off formula, what are the general guidelines for ensuring proper nutrition as he slowly expands his repertoire of foods?
