These signal secure bonds. Pace varies; steady connection matters most, and a gentle check helps if joyful connection or stranger awareness is absent by 12 months.","answer_md":"*Around the first birthday, your baby's feelings begin to show up in beautifully clear ways — and that's exactly what we hope to see.*\n\n## In short\nBetween 9 and 12 months, most babies show warm attachment to familiar people, may become shy or wary of strangers, look to you to gauge how to feel about new things, and protest at separation. These are healthy signs that your baby is forming secure bonds. Every baby's pace varies — what matters is steady warmth, connection and progress over time.\n\n## What you may notice\n- **Joyful connection** — your baby smiles, laughs and lights up when you return to the room\n- **Stranger awareness** — clinginess or wariness around unfamiliar faces (a normal, expected step)\n- **Separation protest** — crying or reaching when you leave; this shows a secure attachment, not a problem\n- **Social referencing** — glancing at your face to read whether something new is safe or fun\n- **Sharing feelings** — offering toys, babbling with emotion, seeking cuddles when upset\n- **Expressing preferences** — clear delight at favourite people, games or foods\n\n## The science\nThe WHO ICF describes emotional functions (b152) as the regulation and range of feelings. In this window, your baby is building the foundations of emotion regulation by borrowing yours — your calm, your warm voice and your responsiveness teach their nervous system how to settle. Responsive caregiving is the single most protective influence here.\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 list. If feelings seem flat, or there's no joyful connection or stranger awareness by 12 months, a gentle developmental check is wise.
