C has slept through the night all week. Yay!!!! <:-P

But all week, he has had leaks that he never did before. Mostly just small ones, a damp edge here or there. But this morning he woke up and he was soaked. pants, top, sheet, blanket, everything.
I'm pretty sure I can try a few things to take care of the leaks. Add more of what we are doing, or have a good excuse to buy some fitteds. We use prefolds and hemp doublers at night, and they have been drenched, its not fit or repelling leaks.
But I am wondering why?
Is there some correlation between sleeping more and peeing more? He isn't in the diaper any longer, just asleep the whole time instead if waking up a lot. Is it just a coincidence?

Re: STTN and leaks- at 14 months.
Sounds like an extra doubler or trying fitteds might be in order! Yay for more fluff.
I'm cheap, and skeptical of fitteds getting clean enough. So I'd try an extra insert first and see if that helps. I really like the flip inserts since they seem trimmer than prefolds.
