My 2 week old baby is very strong, he sleeps swaddled below his arms (he doesn’t like to have his arms swaddled & the baby nurse said it’s fine to leave his arms out). We place him to sleep on his back however like I said he’s strong. He lifts his legs in the air and flips himself to his side (I can tell he does this intentionally) then he calmly falls asleep on his side. Is this safe bc I don’t really know how to prevent him from doing this unless I myself never sleep. Not really sure what to do I’m a FTM
