Bitti d'Lish All in Ones Shrinking

Is anyone else having problems with these nappies shrinking in the wash?

hi i did first off, as i was washing them at 60 but now washing at 40 and they seem to be fine. In general they may shrink a little i was told but not huge amounts.

Thanks.
I've been washing them at 30 all the time, so its frustrating that they still shrink. I've had some shrink by 3inches in length, which is alot when they are going around little bottoms!

If they were bought new contact itti, they are well known for doing this and itti recognise they do have this problem.
I have one that shrunk and shriveled when i washed it on a 60 and they wouldnt replace as it was 2nd hand x
