When Do Babies Actually Stand? Real Ages from Thousands of Families
Half of babies stand up by 9 months, based on real entries from the Baby Notebook community. The most common age was 10 months; the middle half fell between 8 months and 10 months.
| Age | Share of families |
|---|---|
| 6 months or earlier | 4.8% |
| 7 months | 11.3% |
| 8 months | 20.5% |
| 9 months | 19.6% |
| 10 months | 22% |
| 11 months | 12.7% |
| 12 months | 6.3% |
| 13 months | 1.6% |
| 14+ months | 1.3% |
Boys and girls: boys averaged 9.1 months and girls 9.2 months.
A later month on this chart is a memory, not a verdict. About a quarter of the families here recorded this one after the middle range ends, and the spread across all of them is wide. If the timing worries you, your pediatrician is the right person to ask.
