Hello and welcome to the tree!
I'm Nichola, mum to 11-month-old Iris.
Amongst others, we use Bumhuggers and Baby Beehinds as night nappies successfully. Though when Iris was about your DD's age and still feeding a lot at night, I did boost them with Easy Peasy hemp boosters, too. I don't use pockets overnight, as DD is too skinny for us to get enough stuffing in a pocket to last overnight without gaping leg holes that leak. Lots of people use bamboo over hemp overnight, I think.
