Can parents get their baby on back on track on their own, or is this something they need a professional for?

Most of the time, children get the developmental skills they need when they are given opportunities to practice. Parents play a huge role in their child’s development, and often can help their child right away. For example, if your child’s screening showed a delay in language, you help your child right away, just by practicing this area of development.

However, sometimes your child may need professional intervention. In these situations, it’s best to work with your healthcare or childcare provider to get resources or referrals to professional agencies who are trained to help your child reach their developmental milestone needs.

The Baby Your Baby program provides many resources for all pregnant women and new moms in Utah. There is also expert advice from the Utah Department of Health and Intermountain Healthcare that air each week on KUTV 2News.
