WOW, you do have a little weer on your hands
Having not read your previous threads I am not sure if I am repeating what has already been said or not.
I would suggest trying a Heavy Wetter Good Night Sleep Tight (GNST). From what I have heard they are great night nappies. I couldn't find anywhere that had them in stock but here is some info:
GNST at The Nappy Bucket
GNST are also side snap so you can have it looser around the waist and tighter around the legs if you need to.
Is the nappy soaked when you take them off or is it a matter of your baby wont go back to sleep without being changed???
I would also suggest trying a wool cover rather than longies to start with if you are concerned about the hassle of changing. You can get a number of wool covers that snappi on or velcro close so it will be a little faster than putting their legs into longies at every change.
No other suggests atm, sorry
