Must have for new parents! After my daughter started rolling, we knew it was time to change to a sleep sack. This one is by far the best. At first, I didn't want to buy it due to price, and now I wish I hadn't waited. This sleep sack kept our little one in the perfect temperature all night long. The fabric is soft and holds up well even after multiple washes. I love that it can be used for such a long period of time. My daughter is really tall, so she didn't get to use it up to 2 years, we stopped using it at 15 months because if wasn't fitting anymore
