Review: Kept our tiny baby warm and she still loves it a year later! - When our tiny daughter was only a few months old we found she was getting really cold at night, dropping her body temp. We were so worried and no pajama or swaddle was helping. We bought this and it turned everything around and now, at 13 months, she loves getting "snuggly wuggly" in her sleep sack ready for bed. It's beautiful quality, smooth texture and enough room for her to grow. Easy to wash. I wish we'd known about it sooner. Would highly recommend.
Review: HIGHLY RECOMMEND - I absolutely love this sleeping bag and so does my little girl. It was recommended to me by a safe sleep group who are super vigilant and fussy with their recommendations. The fabric is very very soft but not flimsy. The zip is strong and well made. It is covered at the ends so its comfortable for little one. It's got two strong press studs at each shoulder and one under each armpit to make it fit well for little babies. It comes with a thermometer so you can check the room temperature so you can dress baby according to the heat. The thermometer isnt the greatest for getting a precise temperature. It comes with a clothing guide too so you know what to dress your baby in for the right temperature so this helps reduce the risk of SIDS it is a bit more expensive than other sleep suits however your paying for absolute quality and more importantly safety. VERY HIGHLY RECOMMEND.

### ⭐⭐⭐⭐⭐ Love it! Warm and comforting.
*by K***K on 8 November 2020*

Feels and looks great! Our little boy wouldn’t sleep for more than 2 hours throughout the night and as soon as we put him in his Woolino sleeping bag, he slept for 5 hours! He was a little bit sick around the collar area but the sleeping bag was quick to dry and it didn’t soak through to his clothes. He also leaked through his nappy and sleep suit but the sleeping bag didn’t absorb anything or smell. I would definitely purchase another one, no need to worry about togs or that I have to keep buying another sleeping bag as every 6 months as he grows.
