My baby is 4.5 months old and she keeps trying to roll to her stomach in her sleep. She has slept on her side since she was a newborn (even though we always put her on her back she would roll to her side). She's still in her bassinet so she doesn't have room to completely roll over but it scares me. We plan to put her in her crib in her room at 6 months but now I'm scared that she'll suffocate once she has room to completely roll over. What do I do? It's giving me so much anxiety
