I would not recommend this product. The arms up position away from the body with the inability to bring the arms in makes for an irritable newborn. With the arms up, my newborn also gnaws at her hands which she would not be able to do with other sleep sacs. Sleepless nights await those who choose to use this product. The sleep sac is way too tight (newborn size barely fits my 7lbs baby), and good luck fitting in if you want to wear something underneath. I had to dispose of this product as I could not justify donating it for others to suffer like my newborn.

This sleep sack has been a life saver. My baby hated traditional swaddles/sleep sacks but at the same time couldn’t sleep with her arms open because of the startle reflex. Swaddle UP solved this issue. It’s also made of a quality fabric that keeps its shape after multiple washes.

While I wanted to love this swaddle I ordered size newborn for my newborn baby...the site only said 0-1 month and my baby was only three days old when I ordered it. However, when the swaddle arrived it had a weight limit of 8.5lbs which my baby already was. If I try to return it I still have to pay shipping and am out a significant amount of money for a product I cannot use. Very disappointed as the weight limit is not listed on the website for this swaddle. I'd love to exchange it for a small but don't feel I should have to pay shipping when the product is not properly listed. I have heard so many wonderful things about this product but instead of being able to try it for my baby I'm out $56 on a product I can't use safely.

This is the best swaddle. He can't Houdini out of it like the others and the zipper makes it so I don't worry about it going over his mouth.
