We've been using Millie moon nappies for 7 months now when they're cheap enough, not had any problems.
Overall they're better then alternatives for ergonomics and sizing since my kid is a giant.
Given this is in Australia but i doubt they change much between here and anywhere else
For clarification when I say ergonomics I mean the tabs etc because I have giant arse hands and the mille moon pull tabs are just easier for me to get at. I don't think it helps the boy sit straight or anything like that
