For night time we use the one in the picture. Zero leaks and he drinks a lot of
I have always used Tesco Fred and flo nappies. Never leaks and so cheap compared to other brands. My little boy is the same, never stops drinking and has 9oz cows milk at 7:30 before bed. I always just put a fresh nappy on right before he goes down to sleep and never have an issue. He is currently in 4+ and I did notice when I went up to size 5 he was damp in the morning 2 days in a row! Went straight back to 4+ and always dry again. So I do think even if nappies are even slightly to big they can easily leak. Hope that helps
We use Aldi mamia and she’s usually in a size 6 for the daytime but at night we pop her in a 6+ and it seems to be doing the trick so far!
I wish I had this problem, my son is a rubbish drinker and he weaned himself off milk before Christmas so we never have any nighttime leaks anymore! We used to use the pampers premium protection pants too but then he started having the odd leak so I was told to use a cloth nappy over the pants just for backup but it kind of coincided with him stopping milk so we didn't get to test the theory but I did hear good things! Fingers crossed for you! x
