About me
As a mother of 2 young children, I always found it hard to easily determine what I should be dressing my baby and toddler in for sleep and naps. Living on the North East coast of Spain where temperatures range from 0–40°C throughout the year, I was forever searching through my Pinterest boards for my pinned sleeping bag TOG guides at bedtime. I wasn't able to find a simple resource based on my own TOG sleeping bags, rather than the standard recommendations, so I did a lot of research and analysed trusted organisations' safe sleep guides and sleep sack companies' recommendations, and built my own calculator. Now it's 1 less thing to stress about at bedtime and my husband and I, and our kids, are all happier for it.
If it even helps out just 1 other parent, grandparent or carer, then it was worth making.
