8 week old sleeping thru the night!

My 8 week old little girl has been sleeping thru the night for 2 weeks now! She lays down between 8-9:30 typically and doesn't wake up until 7-8 in the morning! She's taking short cat naps throughout the day and eats about every hour and a half during the day (trying to stock up I guess!). I feel like it is just a stage or growth spurt but I am definitely enjoying it while it lasts! Pediatrician said that it's perfectly fine, I'm just a lucky momma with a wonderful baby! Hoping she doesn't go thru a sleep regression anytime soon (although I know we probably will :( )
