Less is better, especially for children with limited language — passive screen time competes directly with the back-and-forth interaction that builds communication. Practical approach: keep screens out of meals and the hour before bed, prefer watching together while you narrate, and replace one screen slot at a time with sensory play or outdoor time rather than banning everything at once (which triggers meltdowns). If speech is delayed, ask your therapist for a realistic weekly reduction plan.
