Growing so fast!!!

My lil guy turned 8 weeks yesterday ... It's like he made major progress overnight ... Yesterday he calmed himself down from a crying fit in the car when I couldn't get to him (I usually need to pull over and hold him for a few min to calm him down)... He was fighting falling asleep at bedtime, so I put him in his crib and he didn't cry, fell asleep on his own ... Then he slept for 7 hrs straight ... All of these were first to happen in one day ... I'm so happy and hope it continues , but it's hard facing the reality that they do grow up so quickly
