Stomaching sleeping making me nervous

My 6 month old ( turned 6 months yesterday) keep turning on her belly and it freaks me out at first for about a month she was sleeping on her side now she on stomach and I’m like yikes honey. But when I turn her she gets cranks I give her her pacifier and she turn back on her belly. She looks so comfy but I’m like 😬. And I forgot to put her owlet sock on because we was cuddling and reading she just recently started sleeping 5-6 hours straight so I don’t wanna wake her to put the sock on ugh I just wanna sleep while she sleep but this being my first I’m like oh my. I’m try close my eyes idk y but as I write this im like ok she is fine she know how to move freely. ( she is not nor never have been wrapped at night she hated it since birth)
