Just like a child, won't do what mama asks. Neonatal Nutritionist Bryn Hamilton is next, talking with Mrs. Hemphill about the fact that even though her active son is getting plenty of calories for his age, he's not gaining as much weight as he should. Although he's stubborn about feeding himself, he is using a cup. Trace still doesn't have many teeth in the back of his mouth, so he's pretty much on a soft diet. You want to start with things that will melt in his mouth like Cheetos or graham crackers.

They can usually gum them pretty well. Also, you can do things to grits and mashed potatoes like add whole milk or extra margarine or things like that. She also says that it might be easier to get Trace to consume liquid supplements rather than more food. She later noted that Trace's father is tall and lanky, so simple genetics might be helping keep her son lean. I think you are doing really well.
