8-month baby milestones: what to notice
A practical eight-month guide to movement, object play, shared attention, and babbling between the CDC’s six- and nine-month checklists.
At eight months, many babies are busy combining skills. They may sit more steadily, move a toy from hand to hand, look for a dropped object, enjoy peekaboo, and repeat sounds such as bababa. There is no separate CDC eight-month checklist, and crawling is not a required route to walking. Notice how your baby solves movement and communication problems in their own way.
What to notice at 8 months
This table gives you useful observations, not targets your baby must perform on cue. Development moves in ranges, and a baby may show one pillar before another.
| Physical | Sits with less support, pivots or rolls to reach, and bears weight through the legs when held. |
|---|---|
| Cognitive | Looks for a toy that drops, transfers an object between hands, and bangs two objects together. |
| Social | Responds to their name, enjoys peekaboo, and looks between you and an interesting object. |
| Language | Uses repeated sounds such as bababa and raises or changes the voice during interaction. |
Read the pattern, not one performance
Babies may be lively in the morning, quiet with a new person, or unwilling to repeat a skill when tired. One day without a performance does not mean a skill has vanished. Look across a few routines and record the help you offered. That small pattern is more useful to you and a pediatrician than a score or percentile.
If this age falls between CDC checklists
The CDC publishes checklists at selected ages, not every month. Do not fill the gaps with deadlines you invented. Use the nearest checklist as a conversation prompt and watch the pattern that emerges over days.
Three ways to play without testing
- Hide half of a toy under a cloth and let your baby decide whether to look for it.
- Place two safe objects within reach so your baby can compare, transfer, and bang them.
- Follow your baby’s point or gaze, name the object, and wait for another look back.
A tiny routine you can repeat
- Choose one calm moment, such as after a nap or feed.
- Offer one object or invitation, then wait instead of repeating it quickly.
- Name what your baby did and leave room for another attempt.
- Write one sentence if something is new, then carry on.
Play is an invitation. If your baby turns away, yawns, or becomes upset, stop and offer a break. For sleep, follow safe-sleep guidance and place your baby on their back in their own safe sleep space.
A short record that helps your pediatrician
Record the date, what happened, and how much help you gave. “Reached for the block during floor play; I held it near the left hand” is more useful than “doing well.” Bring your questions and patterns to the next visit.
If you use Emomo, save the observation under the pillar that fits and look again a week later. The aim is to remember real change, not fill every box. A skill that appears in two languages or two routines can be recorded as two parts of the same story.
When to ask
Contact your child’s doctor at any age if a skill they clearly had disappears, several areas concern you, or something feels unusual. If your baby was born prematurely, ask how corrected age should be used for their development.
Frequently asked questions
Are there official eight-month milestones?
The CDC has six- and nine-month checklists, not a separate eight-month list. Use this age to watch skills becoming more coordinated, and avoid creating a deadline between checklist ages.
Does my eight-month-old need to crawl?
No single crawling style is required, and some healthy children never crawl on hands and knees. Look at the wider movement pattern and discuss any concern or regression with your pediatrician.
What does bababa mean at eight months?
Repeated consonant sounds are an important way babies practise turn-taking and speech sounds. They are communication practice, not necessarily words with a fixed meaning yet.
