What Is Core Strengthening? 

Core strengthening focuses on improving the stability and endurance of the muscles in the abdomen, back, and pelvis. These muscles provide essential support for posture, balance, and coordination. Weak core muscles can affect a child’s ability to sit upright, participate in sports, and complete daily tasks like dressing or writing. 

Signs Your Child May Need Therapy for Core Strengthening 

Children with core weakness may show difficulty in maintaining proper posture, performing gross motor activities, or engaging in fine motor tasks that require stability. Below are age-specific signs of weak core strength.

  • 6 months: Difficulty rolling over or sitting without support 
  • 9 months: Trouble transitioning between positions (e.g., sitting to crawling) 
  • 12 months: Weakness in standing or pulling up to stand
