Best absorbent overnight nappies?

[hippityhippityhop]

DS is 4.5 months and in size 4 nappies. He soaks through them every night so I wondered if anyone can recommend some which are super absorbent? We have tried Aldi and Asda so far. Thanks

The only ones I found that don't leak for DS (5 months) are the Sainsbury's own brand ones. They have an elasticed back on them which seems to help a lot.

Thanks @Biribiftz. Will try these!
