The typical 12-month-old child will demonstrate certain physical and mental skills. These skills are called developmental milestones.
All children develop a little differently. If you are concerned about your child's development, talk to your child's health care provider.

A 12-month-old child is expected to:
- Be 3 times their birth weight
- Grow to a height of 50% over birth length
- Have a head circumference equal to that of their chest
- Have 1 to 8 teeth
- Stand without holding on to anything
- Walk alone or when holding one hand
