I use Hollow Oaks for Amelie but I have to boost them as she is quite a heavy wetter at night. I just put in hemp booster with them. What I like about Hollow Oak is they are very trim. We didn't get on with bedbugs at all & they are quite bulky
Out of the two I'd go for Hollow Oak Night nappy but I do boost it if she's drunk a lot - it would make a fab daytime fitted though! Hollow oaks are very trim - I find bedbugs quite bulky comparatively but that's probably the microfibre, it may be different with no microfibre?
