We like Pumpkin Pants, they have great designs Emma is in a M/L Bedbug with a L fleece soaker. You may need to size up with night nappies I think. There was a couple of Ms in Classifieds recently I think
One night or one day & then just bung them in a normal wash. You don't have to put them in the nappy wash which is really handy if you are trying them out & only have 1. Just make sure the nappy is well boosted & the vest isn't too tight on top as fleece can get compression wicking.
