Toddler formula

Karinne

I got my 14 month old a can of toddler formula today. He eats regular meals and I'm weaning him from nursing. I mainly got it to fill in any nutrients he may be lacking because while he "eats" regular meals he mostly throws his food on the floor. I'm concerned he's not getting all the nutrients he needs. So should I use the formula in the place of his regular drink with meals? Do I replace breast milk with the formula?
