These are the warm, early roots of [communication](/communication) — and there's a wide, healthy range of normal at this age.\n\n## What you may notice\n**Listening & understanding**\n- Turns head or eyes towards your voice and to sounds\n- Quietens or brightens when spoken to gently\n- Startles less, but still notices sudden loud sounds\n\n**Making sounds & connecting**\n- Coos and gurgles, then strings vowel sounds (\"aah\", \"ooh\")\n- Laughs out loud and squeals with delight by around 4–6 months\n- Smiles back at you and holds warm eye contact\n- Takes \"turns\" — you talk, baby answers with a sound, you reply\n\nRemember, milestones are guides, not deadlines. Babies arrive on their own timeline.\n\n## A gentle watch-point\nIf by 6 months your baby doesn't smile or respond warmly to you, doesn't make any sounds, or never seems to react to sounds at all, mention it at your next visit and ask for a hearing check — hearing is the foundation of early communication.\n\n## The Pinnacle way\nA clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online checklist.
