I have a night JR but it was made for a secre santa. I'm not sure if Bethy makes them on customs. I have used my normal JR as a night nappy before though with extra boosting. My night one come with a extra hidden layers, a tri-fold lay-in insert and a booster that is wool-backed. I think the best thing to do is contact Bethy and ask.
Generally they're not night nappies unless boosted, but they are very well made and very well fitting, and nice looking nappies which is why they sell so quickly Also generally organic bamboo velour nappies sell very quickly anyway
I use mine overnight,and have recently added an extra bit of boosting too,which the nappy accomadates well, despite being trim. Lovely nappies, and I *believe* that when her web shop opens there will be specific night nappies
