I've always had to boost BH to last overnight on my heavy wetter. Iris used to wear them boosted overnight no problems when she was your LO's age. They're now our emergency, middle of the night nappy change nappies and still just about do the job (heavily boosted with lots of hemp and bamboo, of course!). I think for the price they're quite good value. And quite quick drying because of the flip out booster. That opening also means a decent size pocket for stuffing, which means you can customise to how heavily your baby wets. I don't think they're a bad budget NN.
