My 2 Month Old Average?

My daughter is 2 months old. For some reason I feel like she's developing very quickly. She's held her hed up from day one, since 1 months she's been standing on her feet straight up and down & jumps up & down, she giggles & just coo's alll the time, she sits up, & rolls on her sides, she attempts to hold her own bottle, she's slept through the night since she was 5 weeks old & only takes 2 short naps a day....I know its nothin to be worried about, I feel lucky. But I just wanna know if an average 2 month old is the same.
