If the outside of the WC isn't wet then she is un-likely to feel wet as the fleece on the inside of the nappy is a stay dry lining. I am not so sure your issue is her feeling wet, rather the weeing process or simply waking at night. Perhaps she is use to the routine of feeding and changing and finds this a comfort and cant re-settled without this process??

At that age DS was wetting a BBB and sometimes an additional BBB bamboo tri fold on the outside of the nappy at night. By wetting I mean, nappy wet from front to back, every part. He however didn't wake when he felt wet so it wasn't a huge issue.

BBH wool covers are very good and can take some of the moisture from the nappy so if the nappy was wet the cover would start taking some of that on to avoid the baby feeling like they were sleeping in a puddle.

Unfortunately the more absorbent the nappy is the more layers it has therefore will be bulkier.
