8 Months Old Development
Content reviewed against published CDC, WHO, AAP guidelines
Last reviewed:
Object permanence clicks. Your baby knows things exist when hidden, which drives both exploration and separation anxiety. The 8-month regression may arrive.
Key takeaways
- Crawls well (or uses alternative locomotion)
- Understands object permanence (looks for hidden toys)
- Separation anxiety peaks for many babies
- Moving toward more textured foods — soft pieces, mashed food with small lumps.
- The 8-10 month sleep regression may occur.
“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.”
Physical development
- Crawls well (or uses alternative locomotion)
- Pulls to standing at furniture
- Developing pincer grasp (thumb and forefinger)
- May begin cruising along furniture
Cognitive development
- Understands object permanence (looks for hidden toys)
- Points at objects of interest
- Explores how things work (buttons, levers, doors)
- Watches your face for cues on how to react to new situations
Social & emotional
- Separation anxiety peaks for many babies
- Clings to familiar adults
- May be fearful of strangers
- Understands "no" (though may not always comply)
Feeding
Moving toward more textured foods — soft pieces, mashed food with small lumps. Self-feeding with fingers is developing. Continue breast milk or formula.
Sleep
The 8-10 month sleep regression may occur. Pulling to stand in the crib, separation anxiety, and new cognitive skills can all disrupt sleep.
Common concerns at this age
Activities to try
- Play hide-and-seek with toys under a blanket
- Offer finger foods to practice pincer grasp
- Read books and let baby turn pages
- Play with containers — filling and dumping

Bottom line
Every baby develops at their own pace. The milestones listed for 8 months old are typical ranges based on CDC and AAP guidelines. If your baby hasn't reached a milestone, it doesn't necessarily mean something is wrong — but talk to your pediatrician if you have concerns.
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.
