Assymetrical crawling?

Katie|👶🏼🐶🐶|

So my 9 month old (almost 10 months now) was crawling on all fours since the day he turned 7 months and for the past week or two he’s been crawling with one foot planted on the ground.. I thought it’s cause he’s getting ready to stand but I googled it and was horrified by the results.. eye problems? Autism? That can’t be right.. is anyone else’s baby crawling this way? What do you think causes this?
