Your 7-Month-Old: Cause and Effect, and the Run-Up to Crawling
By the Growbaby team · Published Aug 4, 2026
Written against AAP, CDC and WHO guidance. How we write these guides
At a glance
- Cause and effect clicks: push this, that happens, do it again.
- Banging two objects together is a genuine cognitive step, not just noise.
- Many babies get into a crawling position and rock before they travel.
- Standing while held takes real weight through the legs now.
- Repetition is the point; the hundredth time is as informative as the first.
The dropped spoon is not defiance. Around now your baby works out that their actions produce reliable results in the world, and the only way to confirm a rule is to test it repeatedly. Every drop is a small experiment with the same encouraging outcome.
Physically, this is the run-up month. Rocking on hands and knees, pushing backwards instead of forwards, and a lot of visible frustration are all normal parts of assembling a crawl.
What is new this month
The dropped spoon is not defiance. Somewhere around now your baby works out that their own actions produce reliable results, and the only way to confirm a rule is to test it repeatedly. Every drop is a small experiment with an encouragingly consistent outcome.
Banging two objects together belongs to the same discovery. It needs both hands doing different jobs at once, and it produces a result your baby caused. Physically this is the run-up month: rocking on hands and knees, pushing backwards instead of forwards, and visible frustration are all part of assembling a crawl.

Frequently asked questions
Many babies get into a crawling position and rock for weeks before they travel, and the crawl itself usually arrives somewhere between six and ten months. Some babies never crawl in the classic way and go straight to cruising, which is not a problem in itself: the CDC does not list crawling as a milestone at any age.
It is a genuine cognitive step rather than noise for its own sake. Bringing two things together at the midline and making something happen is cause and effect being tested, and the hundredth repetition is as informative to your baby as the first.
On its own, no. What matters more than the style of movement is that your baby is finding some way to get across the room and using both sides of the body to do it. Anything that worries you is worth raising at your next checkup.
