Thanks for all the ideas!
I guess I will go for a Weenotion night nappie with longies instead of pjs.
Okay I just like the look of that and if I get it right it must me absolutely bombproof
Tried the night booster with the pop in but the nappieis too little when I just that.
Pop n Gro was the one I tried this morning, hell, megaleak in 3 hours with both boosters and nasty stripes on my daughter.
Never heard of the Genesas Forge night nappy (AI2) and Sweet Nights but will look for that too.
Oh and I will give the Minki's another try since I happen to have 4 of them
