Asthma is a health problem that tends to run in families where overly sensitive airways swell, tighten, and produce too much mucus. Who’s at the highest risk leaving site icon of getting asthma?  Children who were born premature, live with smokers, or have parents or close family members who have allergies or asthma are more likely to develop the disease. Health experts are still trying to figure out what causes asthma to develop in susceptible children, but asthma seems to result from both a family tendency and exposure to environmental triggers.

About half of children with asthma develop symptoms by age two, and about 80 percent will have symptoms by age five. But detecting asthma in babies and toddlers can be hard. When very young children get certain lung infections, their tiny airways easily fill with mucus. This can lead to the wheezing sound that may sound like asthma but isn’t. instead, look for these symptoms each time your child gets a cold or viral illness:

Tips for managing triggers

Wash bedding regularly in hot water.
  • Indoor mold. Mold and mildew grow in damp areas. Depending on the time of year and area you live in, keep indoor humidity levels no more than 50%. Scrub any visible mold from hard surfaces with water and detergent. Dry the area completely. Repair and seal any leaks.
  • Furry animals. Ban dogs and cats from your child’s room. If your child has a pet hamster, rabbit or guinea pig, have someone else clean the cage.

How can allergies be treated?

Talk with your child’s doctor about allergy treatments. Options include:

  • Nasal sprays. Steroid nasal sprays are now generally the main treatment for allergies. They are safe when used as directed and you can buy them without a prescription.  Check with your child’s doctor before giving them to your child. Prescription drugs. Your child’s doctor has some options in treatments. You can talk through the options during the exam.
  • Allergy shots. This treatment is generally reserved for severe allergies when other treatments don’t work. It helps the immune system become less sensitive to allergy-causing items. Regular visits to the doctor’s office are required for at least three years. Children with severe asthma may not be able to take allergy shots.
