If your toddler is having fewer bowel movements than usual or has a hard time passing stool, he may be constipated. Constipation can be caused by many things, especially during the toddler years when your child may be learning to use the toilet.

As a parent, you want your child to have the most nutritious diet possible. Because you take a multivitamin every day for your health, you wonder whether your young child needs vitamin supplements, too.

By the time your child reaches 2 years old, your days of cooking special meals and nursing throughout the night are generally over. According to the American Academy of Pediatrics, a 2-year-old can eat the same food as the rest of the family, consuming three meals and one or two snacks a day.

Virtually all toddlers experience bouts of diarrhea, which can be caused by infections, food intolerance, parasites, antibiotics and even by drinking too much juice. Most cases of diarrhea are mild and can be treated in just a few days with home care.

Feeding a vomiting toddler can be difficult, but it is necessary to help him recover. Even if the toddler throws up the majority of the liquids and food that you feed him, he is still reaping some nutrition from those items. According to the book "What to Expect: The Toddler Years,"

Feeding a toddler can be challenging. Toddlers are often picky about what they eat, making it difficult for him to get proper nutrition. When a toddler is underweight, or has slower than expected weight gain for his age, parents should watch his beverage intake and assess the type of food that he or she does eat.

As the rate of growth slows down and the need for independence starts emerging, many toddlers have a low appetite and become picky eaters. This is a normal developmental stage that most children will grow out of.
