Great product!

These sleep sacks have been a game changer for us. Baby sleeps through the night. Also love the fact that he won’t grow out of it in a few months time like other sacks we used before buying this one.

Absolutely worth the money

We absolutely love our sleeping bag. It has really helped transition our baby out of a swaddle, he loves the security it gives him. During this recent hot weather it’s been so nice knowing he has the consistency of one sleeping bag and it’s really helped his sleep, in previous hot spells we got very little sleep at all as we couldn’t get his comfort and temperature levels right. Our only regret is not buying one sooner. Couldn’t recommend it enough. Without sounding cliche he even smiled as we put him in it last night!

Great sleeping bag

Very high quality and should last a long time. A shame not meant to wash often as it often needs it due to nappy leaks etc. Only 4 stars as quite expensive!

L Marques

Amazing fabric and functionality! Our baby’s sleep has improved greatly! 5 stars !

Excellent product and customer service

We’ve been using the sleeping bag for several months and can safely say it’s worth the money. My baby went from waking every two hours to once/twice a night. I know other factors play into sleep but I really do think this sleeping bag makes a huge difference. The customer service is also fantastic with quick responses, even after hours. Would recommend to any parent.
