I came across this personalized eating plan calculator for preschoolers on a government site. This calculator calculates how much of what a child should eat based on their gender, age, and physical activity and generates a personalized plan for your child. It’s a pretty nifty tool. Check it out at Mypyramid.gov.
I tried it out for my almost 2 year old daughter and this is the printout I got. Keep in mind, this tool only works for children 2 or older.
