Over the past two nights, I transitioned my baby out of her swaddle. It was actually a lot easier than I thought and she's still sleeping through the night just like before!

Here's my question though. Can she sleep in just her sleeper, or does she need a sleep sack? She always wakes up warm, and is a warm natured baby. I'm afraid that she'll get too hot in a sleepsack. Everything I've read seems to point in that direction though. Any advice would be great!
