Unlike a simple delay, loss of skills needs a prompt medical check with your paediatrician first, not a wait-and-see. Only a clinician can confirm.","answer_md":"*When a baby who was reaching, babbling and beaming seems to quietly step back from skills she had, a parent's watchful love is exactly right — and acting early matters.*\n\n## In short\nDevelopmental regression means a baby loses skills she had already gained — rather than simply being slow to reach the next one. In a 6-to-9-month-old, this might look like babbling that fades, eye contact or social smiling that dwindles, or sitting and reaching that slip away. Because losing skills is different from a delay, it always deserves a prompt medical check — not a wait-and-see — so the cause can be understood and support can begin quickly. This is a signal to act gently and soon, not a reason to panic.\n\n## Gentle signs to notice\n**Communication and sounds**\n- Babbling (\"ba-ba\", \"da-da\") that was emerging and has now reduced or stopped\n- Going quiet or much less vocal than she was a few weeks ago\n\n**Social connection**\n- Less eye contact, fewer social smiles, or seeming to \"tune out\" from faces and voices\n- No longer turning to your voice or enjoying peek-a-boo the way she did\n\n**Movement and use of hands**\n- Losing head control, or no longer sitting with support she had managed before\n- Stopping reaching for or holding toys she used to grasp\n- New stiffness, floppiness, or unusual repetitive hand movements\n\n**Feeding and alertness**\n- New difficulty feeding, swallowing or staying alert\n- Any seizures, staring spells, or sudden changes in tone\n\n## Why losing skills needs a prompt check\nA gap in *reaching* a new milestone is common and often resolves. But *losing* a skill that was already present is a different signal, and at this young age it is best looked at promptly by a doctor first — usually your paediatrician — to understand the cause before any therapy plan begins. Most worries turn out to be reassuring, and where something does need attention, early action gives your baby the very best start. Trust your instinct: if a skill has slipped away, seek a check soon rather than waiting.\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 a checklist or a worried evening online.
