Rolling in sleep

Both my babies have slept on their belly’s since just a few days old, it’s just what they preferred. If they have a safe sleeping environment I would say it’s totally fine, especially now your LG it’s a little bit older. My opinion is if they can lift their head up and turn it to the side, which they can usually do from about a couple of weeks old, they are totally fine 💕
Both mine sleep like logs on their belly’s!

My mum also put me and my sister to sleep on our belly’s as new borns, as it’s just what we preferred, so she said.
