It was time to transition out of a swaddle and I was hesitant to buy the woolino because of the price point. After reading the reviews I decided to give the brand a try. My son immediately took to it! The balloon pattern is our 2nd purchase and it is adorable! I’m so glad I don’t have to worry about sizing up for a while or change sleep sacks with the seasons. 100% worth the price.

This is like magic. First time our 3 month old wore a woolino to bed, she slept the whole night and has been loving them ever since. Can’t say enough good things, now here’s to hoping it lasts until she’s 2!

Sleep bags are very well made and love the new prints. Just received the construction trucks and hot air balloons.
Customer service is great.
