Yes I don't think she's a particularly heavy wetter at night actually! She normally has a full nappy in the morning but not on the verge of leaking. And during the day she can sometimes go up to 4-5 hours (like if she falls asleep for an hour or 2 after already having it on for a couple of hours, not because I don't change her!), yet other times she'll soak/leak a nappy within an hour.
I hope that doesn't mean she's got to the power wee stage already! Although she's such a greedy guts it wouldn't surprise me!
