Month 15
Quick answer
What is my baby up to at 15 months old?
This month, following a simple instruction on the first try is a genuine milestone.
What's developing
Motor
Many toddlers are walking steadily by now, some starting to try running or climbing.
Communication
Following a simple one-step direction ("bring me the ball") is common for many toddlers around this age.
Social
Combining a word with a gesture, pointing plus a sound, to communicate a want is typical.
Try this together this week
- Practice simple one-step instructions during play, celebrating every success.
- Offer safe, low climbing opportunities (a soft step, a low cushion) under supervision.
- Play matching or sorting games with large, safe objects.
- Keep expanding vocabulary through daily narration and repetition.
What parents often notice
Some fifteen-month-olds are already running everywhere, while others are still cautious, careful walkers; both are common temperament and pacing differences, not a motor gap.
