My son is 21 months old and we've been using a version of a Halo sleep sack or swaddle since he was born. I LOVE THEM. They have held up so well! I have cotton and fleece and find that they wash well and are easy to put on / take off. We have had no issues with zippers and things - other sleep sacks have left us with plenty of mishaps (zipper malfunction, etc). I have never had that with Halo products. Worth the money!
I've been using this for years and even in the harsh winter months it doesn't dry out my skin like other cleansers. I have tried "fancy" cleansers but this one works so well there's no need to go for the expensive stuff.
