How does one find out about these stockings before they happen? I keep finding out just after! (I should check here more often for a start, probably!)

My sis is in the UK atm and has offered to get me nappies for Christmas! She knows me well So, any suggestions for good UK/European nappy brands I should ask for? DD seems to have a skinny waist compared to the size of her things and rise, and is a pretty heavy wetter. Natural fabrics next to skin are also better for her. TIA!
