Before you use this guide: Every baby grows and develops at their own pace, and healthy babies vary a lot. Weights are WHO medians at the start of the month, not targets. If your baby was born early, use their corrected age. This is general information, not an individual medical assessment.

How your baby is developing

At ten months, many babies are on the verge of walking. They may crawl fast, pull themselves up to standing, and cruise along furniture. Others are happy sitting and playing, and some stay put until close to their first birthday. Walking can start any time between about 9 and 18 months and is still normal.

Communication is growing quickly. Many babies this age wave, clap and point at things they want, and they begin to understand simple words and phrases like “no”, “bye-bye” and their own name. They may babble with the rhythm of real speech and imitate sounds and gestures.

Milestones to look for

These are skills that many babies show around this age. Some will come earlier and some later, and missing one is not usually a cause for worry.

Keeping your baby safe

Looking after yourself

Your baby is becoming more independent, and it can feel like a mixture of pride and worry. Enjoy the new skills and keep your expectations flexible.

If you are returning to work or arranging childcare, build in time for your baby to settle with new carers gradually.

When to ask for help

Talk to your health visitor or doctor if your baby does not sit without support, does not crawl, bear weight or pull to stand by about this age, does not respond to their name or to your voice, does not babble or use gestures, or has lost skills they had. If your baby has a high fever, is difficult to wake, is breathing fast or hard or has a rash that does not fade under a glass, seek urgent care.

Trust your instincts. If you are worried about your baby at any age, contact your doctor, health visitor or local emergency number.
