What if the best therapist for your child is… another kid?

When we think about therapy, we picture adults guiding children. But one of the most effective early intervention strategies flips that idea: peer-mediated intervention (PMI) trains typically developing children to become social bridges for kids with developmental delays.

Here's how it works. A therapist coaches a peer — often a classmate or playmate — on simple strategies like offering toys, asking questions, and waiting for a response. The peer isn't "fixing" anything. They're just being a slightly more intentional play partner. And because the interaction feels natural rather than clinical, children with delays often respond more readily than they do in structured therapy sessions.

Research shows PMI is especially powerful for building social communication skills — things like joint attention, turn-taking, and initiating play. A landmark study found that children who received peer-mediated support made twice as many social initiations as those who only received adult-led intervention. The magic ingredient? Kids naturally model age-appropriate behavior in ways adults simply can't replicate.

The best part is that it benefits both children. Peers develop empathy, patience, and leadership skills, while children with delays get practice in the exact environment where they need those skills most — with other kids, during real play.
