DS is 21 months old and currently wearing pampers size 5 baby dry nappies at night. He's also been in size 5+ active fit at night. But about once or twice a week he wakes up around half five/six ish in the morning totally wet through. He's disorientated and not really awake, upset at being changed, but then too awake to get him back to sleep. (And also, I'd rather be asleep at this time!)
Are there any better nappies specifically for nighttime? Or a brand that might be more absorbent?
