12 Months Milestones
Content reviewed against published CDC, WHO, AAP guidelines
Last reviewed:
Twelve months is a magical time - your baby is transforming from an infant into a toddler. But remember, the "first birthday" is not a deadline. Walking, talking, and other milestones all have wide normal ranges that extend well past 12 months. Some 12-month-olds are walking and saying a few words; others are still cruising and babbling. Both are perfectly normal. Focus on the overall trend: Is your baby learning new things, even if slowly? Are they curious and engaged? Those are the most important signs. And always remember - you are doing a great job. The fact that you care enough to check says everything.
Key takeaways

- Fine motor: Refined Pincer Grasp
- Language: First Words
- Social-emotional: Waving Bye-Bye
- Cognitive: Simple Problem-Solving
“Skills such as taking a first step, smiling for the first time, and waving 'bye-bye' are called developmental milestones. Children reach milestones in how they play, learn, speak, act, and move.”
Your baby grabs onto furniture and pulls themselves up from sitting to standing.
What it looks like
Baby grabs the edge of a couch, coffee table, or your hands and hauls themselves up to standing. They stand there holding on, looking proud. They may plop back down or slowly lower themselves.
Typical range
When should I worry?
This is normal
By 12 months, most babies are pulling to stand. Some are already cruising along furniture. If your baby just started doing this, they are right on track.
Mention at next visit
If your baby is not pulling to stand by 12-13 months, mention it at your next well-child visit.
Call your doctor
If your baby cannot bear weight on their legs at all, or has lost the ability to pull up, call your pediatrician.
Cruising Along Furniture
Your baby walks sideways while holding onto furniture for support.
What it looks like
Baby stands at the couch and takes sideways steps while holding on, moving along the length of the furniture. They might move from one piece of furniture to another if things are close together.
Typical range
When should I worry?
This is normal
Cruising is a bridge between standing and walking independently. Some babies cruise for weeks before taking their first solo steps, and others barely cruise at all before walking.
Mention at next visit
If your baby is not cruising or showing interest in moving while standing by 13-14 months, bring it up with your doctor.
Call your doctor
If your baby was cruising and has stopped, or cannot stand even with support, contact your pediatrician.
Your baby may take a few wobbly steps on their own, or they may not be there yet - both are normal at 12 months.
What it looks like
Baby lets go of the furniture and takes one or two unsteady steps before grabbing on again or sitting down. They might only do this occasionally. Many 12-month-olds are not doing this yet.
Typical range
When should I worry?
This is normal
The average age for first independent steps is around 12 months, but the normal range extends well past 15 months. Many perfectly healthy babies do not walk until 14 or 15 months. This is not a race.
Mention at next visit
If your baby is not walking at all by 15-16 months, bring it up at their next visit.
Call your doctor
If your baby cannot stand even with support by 12 months, or has lost the ability to stand or cruise, call your pediatrician.
