Baby teeth don't remain in your child's mouth forever. These temporary placeholders, which first begin to erupt around the first half-year of your child's life and start falling out around the age of 6 years, require diligent care. Problems result when your child loses baby teeth too early -- and some of these complications can be serious.

While certain symptoms your child experiences may provide clues for a simple and quick diagnosis, vague symptoms can be harder for you to identify. Although you may have heard about individuals having an illness called adrenal fatigue, MayoClinic.com advises that the term adrenal fatigue is not a true medical diagnosis. Instead, it is a term that some health books and alternative medicine practitioners use to describe a group of nonspecific symptoms.

Milk allergies are one of the more common food allergies seen in infants and children. Between 2 and 3 percent of babies are allergic to cow's milk formula, according to KidsHealth. If you breastfed exclusively until your child took his first steps and graduated to toddler-appropriate food, his milk allergy may have flown under your radar.

Allergies can affect anyone, regardless of age, although they are generally more common in children, according to the University of Maryland Medicine.

Talk to your doctor about the best type of pediatric medicine to use when treating your child's allergy symptoms.

Between 3 to 5 percent of healthy children between the ages of 9 months and 5 years will experience a seizure due to fever, according to MedlinePlus. Within this age group, toddlers have the highest incidence of febrile seizures. It is important to seek medical care if your toddler has a seizure.

The next time your child brings home a letter from school detailing the latest lice infestation, don't panic. Common parasites, head lice infest the scalps of millions of children every year. According to the U.S. Food and Drug Administration, children between the ages of 3 and 11 years account for six to 12 million cases of head lice infestations annually. These small insects can spread throughout schools and households.

In normal amounts, ear wax (cerumen) provides protection from bacteria and acts as a self-cleaning agent and lubricant, according to the American Academy of Otolaryngology. However, once ear wax builds up, it can cause discomfort, partial hearing loss, tinnitus, odor, itchiness and dryness of the ears. If your child experiences one or more of these symptoms, it's time to clean up his ears. Fortunately, you can perform natural remedies to remove ear wax.

When a kid has symptoms such as sneezing, headache, dizziness, hoarseness or a cough, it can be difficult to know if they're symptoms of the common cold or an allergy. The difference is that colds are the direct result of a virus, whereas allergies are a defense mechanism developed by the body to protect against allergens such as dust, dander and pollen. While diagnosis is best made by a physician, being able to tell the difference between a simple cold and a full-blown allergy can help you play a proactive role in helping to relieve your child's symptoms.

While older children can tell you when they feel sick, toddlers may not be able to verbalize how they are feeling. Understanding which symptoms signal the beginning of the flu, rather than a common cold, can help you determine the best methods of treatment. Although the flu is common during childhood, some cases require medical treatment.

Finding foods that appeal to a toddler is difficult enough when he is healthy, but keeping him well-fed when he has the flu can be even more challenging. While children commonly catch contagious diseases such as colds and flu, it is important to contact your pediatrician when children under the age of 2 develop flu-like symptoms.
