If you have read anything about the Halo, you know why I bought it! It swaddled baby, keeps them feeling like Mommy is holding them, safe and secure! Now as soon as she puts it on him at night, at bedtime, he smiles and is asleep within a couple minutes! Baby sleeps the entire night, and has from just a couple weeks old! If Baby wants to break away from the Halos Swaddle, he can, and does. This is a miracle item, and a must have for every infant! Go and read more about THE HALO! I wish they had them when my kids were babies! This is the second one I bought, the first was a heavy winter fleece one, this is a spring/summer cool cotton one! I can't say enough about this item, you simply must order one for your baby, you will be so happy you did! You won't believe it!
