I think Rufus is a heavy wetter, although I do think it is begining to improve now.
It's mainly overnight I notice it as a problem, he went into dedicated NN's at 6 weeks because he was waking up sopping wet and changing him was making him wide awake and not want to go back to sleep, until 12 weeks we could manage with HL Bedbugs but at that point they stopped being absorbant enough, they were wringing wet & making him sore, adding a LL Bamboo booster between the nappy and the wrap helped for a few more weeks & then we had to do a complete stash overhaul, I weighed his nappies as suggested by Ems so I could get custom absorbancy, I forget the weight difference now but I was amazed at the difference. I would call out-peeing a nappy it being completely saturated, with wetness pooling in the wrap and being able to wring lots of pee out of it ... his nappies are like this every morning, although now with our PK and LLS there is no longer pee pooling in the wrap.
During the day a nappy will last 2-3 hours with the exception of the first one of the day which will be 1-2hrs max.
I use no MF in any of his nappies, they are all bamboo, hemp & zorb. We can't really use anything other than fitteds and wraps as we get leaks with AIO's/Pockets etc ... although we are now trying again and have had one or two successes, but wouldn't be confident enough to use them out of the house or when someone else is looking after him.
He has taken the same amount of milk (5x 7floz) since he was 10 weeks which I suppose will account for his extreme heavy wetting when he was younger and perhaps why it is calming down slightly now (although not overnight) he has a bottle at 7pm and goes into his NN about 10mins before, another bottle at 11pm and then I get him up in the morning at 7am and change him immediately.
