I've come to the conclusion that no matter how hard you try to instill healthy eating habits in your kiddos, it is very hard to compete with the built in basic food groups that these human vacuums come with.
First off, Gerber Puffs are a complete food group all of their own. According to babies, they are a perfect substitute for breakfast, lunch, or dinner and a preferred snack at any and all times of day.
Following closely behind Puffs is the highly nutritious biter biscuit food group. This widely varied group consists of all types of easily dissolved starches compacted into a handheld bar of sorts. These also are required at any and all times of day.
Once a certain number of teeth have a appeared, babies naturally graduate to more complex food groups. The third inborn food group is peanut butter and jelly. This food group may be achieved with crust on or off.
The final naturally built-in food group is sugar...all forms. Kiddos seems to require a ton of this stuff for basic functioning. They claim to need at least 6-11 servings a day and will except anything from donuts to sugar packets to meet their requirements.
Eventually other food groups will appear, chicken nuggets, mac 'n cheese, pizza, etc. Parents, enjoy retraining this in-born food pyramid...around here, it's a work in progress.
