Tie Walking Toddler

Hi,

My almost 2 year old has been walking on his own for about 7 months now. In the last week or two we have noticed him walking on his toes throughout the day. It’s happening maybe 30% of the time and happens both in shoes and barefoot. I know 30% of the time isn’t a huge amount, but both my husband and I noticed and don’t remember our older son doing it.

I’m curious if this is a normal thing and he’s practicing balancing or some other budding skill?

As a little background/aside, he has an asymmetrical crawl that never really resolved despite PT

UPDATING TO ADD - he was grabbing his feet and sort of complaining of pain for a few weeks before the toe walking started. We assumed it was growing pains.
