Sleepwalking or just not remembering?

Okay so this has happened a few times now. The last memory I have at night would be nursing my son and then I’ll wake up and I’m in bed and I freak out because I think I put him in bed with me accidentally but he’ll be sound asleep in his crib.

I don’t remember putting him back at all. I’ll wake up so confused 😅

Like do I fall asleep while nursing and then somehow put him back? Lol I’m so confused and just a tiny bit concerned. It doesn’t happen every night.
