I bought this in a bundle with the babymoov dream belt. They literally are a dream team for sleeping well. I use this pillow to prop between my knees to support my hips and backs during sleep on my side now that bump is bigger. The shape of the pillow means it’s compact and sits really well between knees. It’s supposed to be useful for helping with baby feeding when baby arrives (amongst other uses). So far I’m so pleased I bought it- it’s filled with lovely soft squishy material and is so lightweight so easy to carry around which is so important when pregnant. 10/10!
