dry diaper after 6 hrs sleep!?

luisa
My baby girl is 12 weeks old and since a couple of weeks she's being sleeping 5-6 hrs at night which its amazing I change diaper and feed her right before 11 and she wakes up dry at 5am it is normal!??? 
During the day she gives me 4-5 wet and sometimes soaking wet diapers!?  So I know she's not dyhadrated but is kind of weird to me!?
Who else's baby does this!?
