Abit disappointed

I remember always buying cuddlers for my younger daughter and i have never had an issue this was years back and i loved it... I recently had another baby and decided to stick to what i know but i noticed the quality has dropped, the sizes are also alot smaller than what the package says, some nappies in the pack the sticky sides don't work... I purchased them from a local store but obviously lost the receipt and now I can't exchange them for a bigger size... An example i compared the pampers size up to 8 kg against the cuddlers size 4 plus and the difference isn't much... Help 😢i love the brand but the size is an issue
