Is Your 9-Month-Old Not Crawling? Developmental Milestones - Pediatrics

Not crawling at nine months?


Hello Dr.
Hsiao,
I would like to ask about my daughter who is now nine months old but is not crawling yet.
I have tried to assist her in crawling, but she only moves her arms and does not use her legs at all.
When she is lying on the bed, she moves backward.
If she continues not to crawl, will this affect her growth? I found some information online suggesting it might be related to her brain development.

In our pediatric practice, we screen for developmental delays that are more pronounced, such as a 9-month-old who cannot sit up or use their fingers to grasp objects.
In such cases, a referral to a pediatric neurologist for evaluation is necessary.
If a 9-month-old is not crawling but does not exhibit significant developmental delays, we can continue to closely monitor their neurological development.
Additionally, it is normal for some infants to skip the crawling stage altogether and go directly to standing and gradually learning to walk.

It's understandable for parents to feel concerned about their child's developmental milestones, especially when it comes to crawling, which is a significant indicator of motor skills and overall development. At nine months, many babies begin to crawl, but it's important to remember that each child develops at their own pace.
From your description, it seems that your daughter is showing some signs of mobility, even if she is not crawling in the traditional sense. The fact that she can move backward while on her stomach indicates that she is developing some muscle strength and coordination. It's also common for babies to prefer certain movements over others; some may choose to scoot or roll instead of crawling.
Developmental milestones are guidelines that help us understand the typical progression of skills in infants and young children. According to the Centers for Disease Control and Prevention (CDC), by nine months, many babies can:
1. Crawl: This can be on hands and knees or using other methods like scooting.

2. Sit without support: Many babies can sit independently by this age.

3. Pull to stand: Some babies may start pulling themselves up to a standing position.

4. Use their hands to explore: This includes reaching for toys and manipulating objects.

If your daughter is not crawling yet, it doesn't necessarily mean there is a problem. Some babies may take longer to reach this milestone, and as long as she is meeting other developmental milestones—such as social engagement, communication, and fine motor skills—there may be no cause for concern.
However, if you are worried about her development, it's always a good idea to consult with your pediatrician. They can assess her overall development and determine if any further evaluation is needed. They may also provide guidance on activities you can do at home to encourage crawling and other motor skills.
In terms of the concern about brain development, while crawling does help with coordination and spatial awareness, not crawling by nine months does not automatically indicate a neurological issue. Many factors can influence a child's development, including genetics, environment, and individual temperament.
Encouraging tummy time is essential, as it helps strengthen the muscles needed for crawling. You can also create a safe space for her to explore and play, which may motivate her to move. Placing toys just out of reach can encourage her to reach and eventually crawl towards them.
In summary, while it’s natural to worry about your child's development, remember that each child is unique. If your daughter is active, engaging with her environment, and meeting other milestones, she may simply be taking her time with crawling. If you have ongoing concerns, don't hesitate to reach out to your healthcare provider for personalized advice and reassurance.
