Yay go little pet!
I have tried a lot of night nappies. I will be honest and tell you I gave up with DS and haven't even bothered trying cloth at night with DD2.
DS could out wee Niagara Falls, and by the time I got the ones designed for 'heavy wetters' they were so bulky that they weren't comfy for him and they stank.

Genesa Forge make some great NNs as do Bonnibums.
