My baby it’s 6 months old, I was exhausted because she didn’t sleep at all, she used to be awake all night. So I got this sack and I kinda didn’t like it because it was too thin for me, but she slept through the night the first night, it’s very comfortable and softy so she is able to move enough but not reaching her face. The only thing, it stretches too much The fabric it’s good and bad, because it’s getting too big for her already, but I will definitely get another one.
