Toddlers like to binge on one food at a time. They may eat only fruits one day, and vegetables the next.
Since erratic eating habits are as normal as toddler mood swings, expect your child to eat well one day and eat practically nothing the next.
Toddlers from one to three years need between 1,000 and 1,300 calories a day, yet they may not eat this amount every day. Aim for a nutritionally-balanced week, not a balanced day.
