I'm at my wits end. Every night my ds is waking up because his nappy has leaked. It's always on the back as well. I've tried bigger nappies, smaller nappies, tighter nappies, looser nappies but nothing works. It's draining me at this point because every night I'm having to do at least one complete outfit change which obviously wakes him up. Any suggestions welcome. I'm tearing my hair out now.
