I’ve used a rice sack many times at births, but mine was a small square that needed to be held against mom’s back by someone else. It would often be uncomfortably hot on dad or doula’s hands even though it was the perfect temperature for mom. I learned about this pack through our Frontier co-op that also has a washable cover like mine, but that had straps. This way I can more comfortably hold it against a mom’s back, dad can hold it against her while he’s sitting in front of her (around her sides) or a mom can even hold it herself against her back. It also has lavender and chamomile but it’s a very subtle scent. I’m excited to try it soon
