Lots of feedings

Gibbeanski
It's 6:30pm and LO (3.5 weeks old) has already fed 13 times! I don't think it's cluster feeding, because it's not really "10 minutes later", it's more every hour and a half she wants more. I thought they are suppose to be decreasing in amount of feeds? 😱
Sometimes the feeds will be 20 mins and then others 5-10 minutes. 
I'm thinking about introducing a pacifier thinking maybe it will help, but every time I give the boob she actually eats (and not just sucking for comfort), so I'm a little nervous to give her a pacifier in lieu of the boob. 😕
Oi!!!
