No. Children develop speech and communication at very different rates, and many gain functional communication after 5. Two truths matter: keep working on speech, and give him a way to communicate today — pointing, gestures, picture cards (PECS) or an AAC app. Research consistently shows AAC does not stop speech from developing; reducing frustration often helps it. Focus first on joint attention, imitation, and requesting — these are the foundation speech grows on.
