Your pac is definitely too small for pinkies! But don't worry, they grow so fast; in a month or two you will look back at these pictures and think, "Wow! I can't believe how tiny he was!" I second what MeTree said. Even once your pac is big enough, you shouldn't feed more than one pinky every month or so. Opinions will vary, but mice are definitely fattening. Too many mice can lead too obesity, blindness, and other health problems. They also take a lot longer to digest than other foods. Vary its diet with crickets, worms, etc and make sure you use calcium dust, and your little froggie won't be little for long!
