Has anyone used this? It is a duvet set for toddlers, undersheet zips to the duvet which helps with toddlers not falling out of their toddler bed/first bed. It is a bit pricey but I wondered if it was a good transition to using normal bedding from a sleep bag? I am starting to think about moving dd to cotbed without the side on and this could be a half way there solution? Or is it a waste of money as eventually they need to learn to use normal bedding anyway? Dd is 22 months and waking asking to get out of 'snuggle' which is a sleep bag and cotbed early in the morning. Cotbed is on the lowest setting so she can't climb out but not for want of trying! Interested to see what others think of this solution and their experiences....
