Bad nappy

My son has been on the dischem branded nappies for the longest time and it really worked for him however lately the quality of the pack of nappies I've been getting is pathitec every second nappy tend to break or not stick after one pee the nappy burst. This is the first time I've ever experienced this with these initial brand and I wouldn't Wana change his nappy but if this is the quality I would be forced too.
