Breastfeeding Newborn

My little girl is 8 days old and for the past few nights has cluster fed on alternating boob every hour for about 20 min from midnight to almost 5 at which point she feeds on both sides and then takes her first 3 hour sleep stretch. This is my second LO but she couldn't be more different from my son so I feel a little clueless here. Any other moms experience something similar and have advice?

Diaper count is perfect, not colicky, and overall a very good and happy baby.
