Yes, it is normal for an 8 week old baby to pee often. They have very small bladders and very little bladder control. She will likely need to pee every hour and after eating, drinking, playing, and sleeping. Again, it is completely normal and no cause for concern. As far as licking herself, that is also normal. She's keeping herself clean.
