Every diper leaks!

so my little girl is nearly 6 months now and she is around 6kg give or take, she is quite tall and because of that she is also looking sort of slim especially in her hips. Now my problem is that since at least two month every nappy i have is leaking. I have tried every available nappy in the world, i got even shipped from different countries samples of different brands then uk and i also tried 3 different brands of reusable nappies. I have read every advice and did all i can in the world to make them finally stop leaking! of course with negative result now we are using pamper baby dry size 2 because like i said shes bit skinny so size 3 is defo too big yet, but i also tried it! I have tried all brands sizes 2 and 3. I really dont know what to do and in the night i have to change her clothes 2 times unless im lucky and i manage to take it out before it will blast all over her bedding and her. Sometimes we have to give her bath in middle of the night. i have waterproof protection everywhere, on her high chair, stroller, car seat, bouncer and bed. Is there anything I can do? please tell me im not alone in this! i even had health visitor look at how im putting the nappy on but its ok to her. i can say 8 out of 10 nappies i have leaking.... please helllpppp!!!!! 😫💩
