Best nappy brands.

Hi everyone, Help a girl out! Ha. We’ve always been a user of pampers nappies for both our kids- but they are just sooooooo bloody expensive so looking for the best alternatives in the hope of saving a bit of money. My girl is potty trained now but still using nappies for our 16 month old boy. My boy drinks a lot of water so we need a really absorbent nappy that doesn’t leak. Has anyone any recommendations please? Thank you.
