My daughter was born with hip dysplasia and needs to wear a brace for 2 months. These halo sleep sacks were recommended by the doctor for her since the brace fits underneath. They are wonderful! Excellent quality. Large with plenty of room for her to grow into them. And no worrying about blankets in the middle of the night. Keeps her the perfect temp. I went out and bought 3 more after purchasing this first.

Soft and warm, but not too heavy. We love the weight of this sleep sac for colder nights!

Lil one went to this from being swaddled for 4 months. He's freedom. The material is comfy!!!

My 3 month old baby slept for 8 hours overnight for the first time ever while wearing this blanket! Very soft and cozy, I wish I would have found it sooner.

my daughter loves this, so very cuddly for her daughter. It's her daughter favorite to sleep in since it's so soft.

I have really enjoyed the sleep sack for my son. He is five months old and 26-28 inches long and is getting close to growing out of the small size. It zips from the bottom up so it is nice and easy to change his diaper, unless the pajamas he is wearing underneath has the zipper going from top to bottom and then he ends up getting cold during diaper changes. I do not like that aspect, but overall it gives me peace of mind of not letting him sleep with a blanket that could smother him. He is an active kid and as the previous review notes, there is ample room for them to kick and move their legs. They line the arm and neck areas with soft silk-like fabric. It's good quality. I am buying the size up.
