My 6 month old is a amazing sleeper. She has been since she was 2 months old. I’ll put her in her bed with her paci and she puts herself to sleep. Ever since she’s learned how to roll from back to belly and belly to back she’s always trying to sleep on her stomach now. It scares me to death bc they say “back is best” I never had this problem with my son bc be preferred laying flat on his back which was amazing for my paranoia. I flip her to her stomach about 3 times a night just in a worry and she just goes right back to her stomach. I’ve never let her sleep a full night on her stomach which is how she prefers bc it just scares me bc sometimes it looks like she can’t breathe even when she is and is comfortable. Am I fine just letting her be?
