Hello! We have four month old DS on a sola city wedge insert in the seat of the BJ Versa. The versa came with the official bj footmuff but it's so unwieldy for such a small baby and the wedge makes it hard to do the zip up! So I've been looking at cocoon type sleeping bags just for this winter and wondered if anyone had used the kaiser cuddly bag in a pushchair?
