Baby motor development: which milestones matter?
Development varies, but loss of a skill, persistent asymmetry or no independent walking by 18 months warrants professional advice.

Short, reviewed and referenced answers to parents’ questions about child development and pediatric physiotherapy.
Development varies, but loss of a skill, persistent asymmetry or no independent walking by 18 months warrants professional advice.
Always continue back sleeping. Vary awake positions and seek assessment if flattening progresses or head turning is limited.
A persistent turning preference deserves early assessment. Tailored positioning advice and gentle exercises generally lead to good outcomes.
Independent walking usually emerges between 8 and 18 months. Seek advice if absent at 18 months, lost, asymmetric or painful.
Most cases improve with monitoring, nasal saline and hydration. Breathing or feeding difficulty requires prompt medical assessment.
