Just wondering if anyone has used the OSFM in either of these brands on a newborn? I have a heap of the Bambooty OSFM being given as a gift and looking at the Issey Everybear (I think that's what they're called). I'm hoping to get away with not having to buy any sized nappies. I know they can be a bit bulky on a NB but did you find that they still worked well? Thanks!
