Toddlers are usually picky eaters.
Some days they may eat well, and others not so well. I would make sure your child is not getting more than 8 ounces of juice in a day, and no more than 24 ounces of milk daily. I would also recommend a 3 meal a day 2 snack a day schedule. In addition, it may take offering a new food 15 times before they try it.
