Growth is influenced by genetics, nutrition, physical activity, sleep, general health and environmental factors.

Possible warning signs

Loss of previously acquired skills
Poor weight gain or growth
Significant learning difficulties
Early assessment of developmental concerns can help children receive appropriate support when needed.
