Both my babies have always slept on their tummies from birth. Ones almost three and the other just turned one and they are fine. Babies tend to sleep better on their tummies. Just ensure there’s nothing around her head and that her mattress isn’t too soft.
@Kovashya she’s in her bed downstairs in the living room with me
@Alice she’s in a moses basket, she’s not allowed to sleep on the sofa now she can roll
Once baby can roll both ways it’s perfectly fine. If it’s just the one way, it just needs to be supervised is all. My son was doing the same so I would put him for naps on his tummy and turn on the monitor if I needed to walk away. I would just put her straight on her tummy and keep her in sight is all. By this time my son was pushing himself up so I didn’t have too much to worry about.
