baby sleeping position help

Rachael
Ok so I've had two kids last one was 4 1/2 years ago so it's all new to me again lol.  How are u all letting ur baby sleep? I want to get a wedge so she doesn't roll on her stomach as a new born but do I put her on her side in her bed or her back? Can I rotate between them so she doesn't get a bald spot?? Any suggestions welcome!!!
