My girl does that too, she’s 7 months on Friday, I’ve never even thought about linking it to autism, I just thought it’s normal baby behaviour
Normal
Normal, he’s just testing out all his new sensations and body functions
@Rhiannon he also started to open and close his hands too ,is this also OK?
It’s totally normal at 6 months! It’s part of how babies learn about themselves. It can be confusing because a lot of normal developmental behaviour can also be a sign of autism, but not in isolation. You have to look at all the behaviours of the child. Sounds like every else indicates normal development so I wouldn’t worry!
