Anyone else’s baby prefer to lay on one side of their head? My son always wants to lay on his left side of his head: when he’s sleeping, nappy changes and when I’m just laying with him

I’ve tried turning his head when he’s asleep and within 5 minutes it’s back to the left side

When I lay with him I lay on the opposite side to get him to look and he doesn’t

He’s now has a slight flat spot 😪 I’ve tried propping his head with a blanket to wedge his head but it seems to wake him up ( I only do this when I’m awake)

Anyone else’s baby do this? Or experienced this?
